    Purpose: To assess the long-term results of radiation therapy (RT) when added preoperatively to systemic chemotherapy in patients with locally advanced gastric cancer. Methods and Materials: Patients presenting with T3-4 or N+ gastric cancer received two cycles of cisplatin 100 mg/m{sup 2} d1, 5FU 800 mg/m{sup 2} d1-4, and Leucovorin 60 mg twice daily d1-4; one cycle before and one concomitantly with hyperfractionated RT (median dose, 38.4; range, 31.2-45.6 Gy). All patients underwent a total or subtotal gastrectomy with D2 lymph node resection. Results: Nineteen patients were accrued and 18 completed the neoadjuvant therapeutic program. All patients were subsequently operated and no fatality occurred. At a mean follow-up of 8 years for the surviving patients, no severe late toxicity was observed. The 5-year locoregional control, disease-free, and overall survival were of 85%, 41%, and 35%, respectively. The peritoneum was the most frequent site of relapse. Among long terms survivors, no severe (Radiation Therapy Oncology Group Grade 3-4) late complication was reported. Conclusions: The present neoadjuvant treatment does not seem to increase the operative risk, nor the late side effects. The encouraging locoregional control rate suggests that the neoadjuvant approach should be considered for future trials in locally advanced gastric cancer. Also, the frequency of peritoneal recurrence stresses the need for a more efficient systemic or intraperitoneal treatment.

    A link between HLA allelic variants and long-term results of surgery for gastric tumors was established on the basis of a 10-years follow-up of 112 cancer patients (stage I-II--37.9, III-IV--62.1%; radical surgery--44.6%). HLA class I was studied in a lymphocytotoxic test; HLA class II--gene DRBI specificity using polymerase chain reaction of peripheral blood cell DNA. The control group included healthy subjects living in the city of Novosibirsk (n = 341). High frequency of antigens HLA-B41, -DR1, -DR7 (p < 0.01) co-occurred with HLA-A2, -B12, -B13 and -B18 presence (p < 0.05) in breast cancer patients. Clinical manifestations of cancer were shown to develop in HLA-A1, -B8, -B15, -DR3 and -DR5 carriers at early stages. Tumor development at later stages (III-IV) was associated with HLA-A2, -B12, -B17, -B35, -B41 and -DR7. A link was registered between lethality rate, on the one hand, and HLA-A3, -B22, and, in particular, DR4, on the other, while remission of more than 7-years--with HLA-A11, -B13, -B21 and -DR5. HLA-B22/DR3 phenotype involved worse prognosis in radically-treated patients whereas that of HLA-B8/DR3--a better one. PMID:17037033

    Purpose: We retrospectively analyzed the impact of intraoperative radiation therapy (IORT) on long-term survival in patients with resectable gastric cancer. Methods and Materials: From 1991 to 2001, a total of 84 patients with gastric neoplasms underwent gastectomy or subtotal resection with IORT (23 Gy, 6-15 MeV; IORT-positive [IORT{sup +}] group). Patients with a history of additional neoadjuvant chemotherapy, histologically confirmed R1 or R2 resection, or reoperation with curative intention after local recurrence were excluded from further analysis. The remaining 61 patients were retrospectively matched with 61 patients without IORT (IORT-negative [IORT{sup -}] group) for Union Internationale Contre le Cancer (UICC) stage, patient age, histologic grading, extent of surgery, and level of lymph node dissection. Subgroups included postoperative UICC Stages I (n = 31), II (n = 11), III (n = 14), and IV (n = 5). Results: Mean follow-up was 4.8 years in the IORT{sup +} group and 5.0 years in the IORT{sup -} group. The overall 5-year patient survival rate was 58% in the IORT{sup +} group vs. 59% in the IORT{sup -} group (p = 0.99). Subgroup analysis showed no impact of IORT on 5-year patient survival for those with UICC Stages I/II (76% vs. 80%; p = 0.87) and III/IV (21% vs. 14%, IORT{sup +} vs. IORT{sup -} group; p = 0.30). Perioperative mortality rates were 4.9% and 4.9% in the IORT{sup +} vs. IORT{sup -} group. Total surgical complications were more common in the IORT{sup +} than IORT{sup -} group (44.3% vs. 19.7%; p < 0.05). The locoregional tumor recurrence rate was 9.8% in the IORT{sup +} group. Conclusions: Use of IORT was associated with low locoregional tumor recurrence, but had no benefit on long-term survival while significantly increasing surgical morbidity in patients with curable gastric cancer.

    A retrospective study of 149 patients with rectal cancer diagnosed between 1972 and 1979 was undertaken to compare survival, disease-free survival, recurrence sites, and long-term complications of 40 patients who received 4000 to 4500 rads of preoperative adjuvant radiotherapy (radiation group) with those of 109 patients treated by resection alone (control group). After a mean follow-up of 84 months and 99 months, respectively, survival of the irradiated patients was significantly better than that of controls (68% versus 52%, p less than 0.05). Disease-free survival of those patients rendered free of disease by treatment was also superior for the irradiated group (84% versus 57%, p less than 0.005). Local recurrence without signs of distant metastases developed only one-third as often in irradiated patients (6% versus 18%). Distant metastases, alone or in combination with local recurrence, were also less common after radiation (12% versus 27%). Second primary tumors developed in 15% and 10% of the respective groups, a difference that was not statistically significant. When we consider the survival benefit of preoperative radiation therapy, long-term complications were relatively mild. Delayed healing of the perineum was noted in two irradiated patients. Persistent diarrhea was severe enough to warrant treatment in only one case, and one patient required a colostomy for intestinal obstruction from pelvic fibrosis.

    The long-term results of a randomized clinical trial evaluating the effect of postoperative radiotherapy as an adjuvant to radical mastectomy are presented. There were 1115 patients including 27 protocol deviants. The follow-up time is 11-20 years. In the first part a conventional roentgen unit was used, and in the second part a /sup 60/Co unit, with considerably increased dosage and altered treatment plan. Both types of radiation techniques lowered the incidence of loco-regional recurrences significantly, but had no significant influence on the overall survival. The relapse-free survival was significantly improved by /sup 60/Co radiation in Stage II patients, but was unaffected by radiation in the other subgroups. Regarding survival, Stage II patients with medially located tumors seemed to benefit more from /sup 60/Co radiation than those with lateral tumors. A significant increase in the number of deaths caused by myocardial infarction was observed in Stage I patients having /sup 60/Co radiation, indicating that the radiation dose to the heart is of significance.

    Purpose: The aim of this study was to assess beam therapy with low-dose-rate (LDR) external irradiation in a group of patients with breast cancer. Methods and Materials: This trial compared, from 1986 to 1989, patients with advanced breast cancer treated either by conventional fractionation or low-dose-rate (LDR) external radiotherapy (dose-rate 15 mGy/min, 5 sessions of 9 Gy delivered on 5 consecutive days). Results: A total of 21 patients were included in the fractionated therapy arm. At follow-up 15 years after treatment, 7 local recurrences had occurred, 3 patients had died of cancer, 18 patients were alive, 10 were without evidence of disease, and 6 had evidence of disease. A total of 22 patients had been included in the LDR arm of the study. Of these, 11 had received a dose of 45 Gy; thereafter, in view of severe local reactions, the dose was reduced to 35 Gy. There was no local recurrence in patients who had received 45 Gy, although there were 2 local recurrences among the 11 patients after 35 Gy. The sequelae were severe in patients who received 45 Gy but were comparable to those observed in patients treated by fractionated radiotherapy who received 35 Gy. The higher efficacy of tumor control in patients treated by LDR irradiation as well as the lower tolerance of normal tissue are probably related to the lack of repopulation. Conclusion: Although the patient numbers in this study are limited, based on our study results we conclude that the data for LDR irradiation are encouraging and that further investigation is warranted.

    Purpose To observe long-term clinical outcomes for patients with early-stage breast cancer treated with forward intensity-modulated radiation therapy (IMRT), including local control and clinical toxicities. Materials and Methods We retrospectively analyzed a total of 214 patients with stage I-II breast cancer who were treated with breast conserving surgery followed by adjuvant breast radiation therapy between 2001 and 2008. All patients were treated using forward IMRT. The whole breast was irradiated to a dose of 50 to 50.4 Gy followed by an 8 to 12 Gy electron boost to the surgical bed. Results The median age was 46 years (range, 21 to 82 years) and the medial follow-up time was 7.3 years (range, 2.4 to 11.7 years). Stage T1 was 139 (65%) and T2 was 75 (35%), respectively. Ipsilateral breast recurrence was observed in 3 patients. The 5- and 10-year local control rates were 99.1% and 97.8%, respectively. The cosmetic outcome was evaluated according to the Harvard scale and 89.4% of patients were scored as excellent or good. Conclusion The whole breast radiation therapy as an adjuvant treatment using a forward IMRT technique showed excellent long-term local control as well as favorable outcomes of toxicity and cosmesis.

    Purpose: We report the long-term results of a prospective, Phase II study of long-term androgen deprivation (AD), pelvic radiotherapy (EBRT), permanent transperineal prostate brachytherapy boost (PB), and adjuvant docetaxel in patients with high-risk prostate cancer. Methods and Materials: Eligibility included biopsy-proven prostate adenocarcinoma with the following: prostate-specific antigen (PSA) > 20 ng/ml; or Gleason score of 7 and a PSA >10 ng/ml; or any Gleason score of 8 to 10; or stage T2b to T3 irrespective of Gleason score or PSA. Treatment consisted of 45 Gy of pelvic EBRT, followed 1 month later by PB with either iodine-125 or Pd-103. One month after PB, patients received three cycles of docetaxel chemotherapy (35 mg/m{sup 2} per week, Days 1, 8, and 15 every 28 days). All patients received 2 years of AD. Biochemical failure was defined as per the Phoenix definition (PSA nadir + 2). Results: From August 2000 to March 2004, 42 patients were enrolled. The median overall and active follow-ups were 5.6 years (range, 0.9-7.8 years) and 6.3 years (range, 4-7.8 years), respectively. Grade 2 and 3 acute genitourinary (GU) and gastrointestinal (GI) toxicities were 50.0% and 14.2%, respectively, with no Grade 4 toxicities noted. Grade 3 and 4 acute hematologic toxicities were 19% and 2.4%, respectively. Of the patients, 85.7% were able to complete the planned multimodality treatment. The 5- and 7-year actuarial freedom from biochemical failures rates were 89.6% and 86.5%, and corresponding rates for disease-free survival were 76.2% and 70.4%, respectively. The 5- and 7-year actuarial overall survival rates were 83.3% and 80.1%, respectively. The 5- and 7-year actuarial rates of late Grade 2 GI/GU toxicity (no Grade 3-5) was 7.7%. Conclusions: The trimodality approach of using 2 years of AD, external radiation, brachytherapy, and upfront docetaxel in high-risk prostate cancer is well tolerated, produces encouraging long-term results, and should be validated in a

    Objective To identify characteristics associated with long-term survival forepithelial ovarian cancer patients using the California Cancer Registry. Methods A descriptive analysis of survival of all California residents diagnosed with epithelial ovarian cancer between 1994 and 2001 was conducted using patients identified through the cancer registry with follow up through 2011. Characteristics of the patients who survived more than 10 years (long-term survivors) were compared to three other cohorts: patients who survived less than 2 years, those who survived at least 2 but no more than 5 years, and those who survived at least 5 but no more than 10 years. Results A total of 3,582 out of 11,541 (31% CI=30.2%, 31.8%) of the patients survived more than 10 years. Younger age, early stage, low-grade, and non-serous histology were significant predictors of long-term survival, but long-term survivors also included women with high-risk cancer. Conclusion Long-term survival is not unusual in patients with epithelial ovarian cancer, even in those with high-risk disease. Many of the prognostic factors are well known, but it remains to be determined why some patients with advanced stage high-grade cancers survive longer than others with the same histology. These findings are important for patient counseling. PMID:26244529

    Metastasis to the adrenal glands is a relatively frequent observation at autopsy of patients that have succumbed to cancer. Long-term disease-free survival has been reported in patients following the resection of solitary adrenal metastasis resulting from colorectal cancer. In addition, following primary resection for colorectal cancer, solitary metastasis to the adrenal glands is rare, even in outpatients at routine follow-ups. Therefore, adrenal metastasis is usually detected in combination with multiple synchronous metastases at other sites in the terminal stages of cancer. Between 1998 and 2002, 3 patients with adrenal metastasis and other synchronous metastatic sites underwent surgery for adrenal metastasis at the Department of Gastroenterological Surgery at Osaka University. The other synchronous metastatic sites observed in the 3 patients consisted of lung and para-aortic lymph nodes. In total, 2 out of the 3 patients experienced long-term disease-free survival for >5 years following surgery and 1 patient underwent curative resection for recurrence of metastases in the liver and right adrenal gland 79 months subsequent to the initial resection for adrenal metastasis. All 3 patients survived for >90 months. In conclusion, aggressive surgical resection for adrenal metastasis and other metastatic sites resulting from colorectal cancer may result in a survival benefit in selected patients. PMID:27602101

    Purpose: The purpose of this study was to determine locoregional control (LRC), disease-free survival (DFS), and toxicity of high-dose-rate interstitial brachytherapy (HDR-ISBT) in the treatment of locally advanced cervical cancer. Methods and Materials: Between March 1996 and May 2009, 116 patients with cervical cancer were treated. Of these, 106 (91%) patients had advanced disease (International Federation of Gynecology and Obstetrics stage IIB-IVA). Ten patients had stage IB, 48 had stage II, 51 had stage III, and 7 had stage IVA disease. All patients were treated with a combination of external beam radiation therapy (EBRT) to the pelvis (5040 cGy) and 2 applications of HDR-ISBT to a dose of 3600 cGy to the implanted volume. Sixty-one percent of patients also received interstitial hyperthermia, and 94 (81%) patients received chemotherapy. Results: Clinical LRC was achieved in 99 (85.3%) patients. Three-year DFS rates were 59%, 67%, 71%, and 57% for patients with stage IB, II, III, and IVA disease, respectively. The 5-year DFS and overall survival rates for the entire group were 60% and 44%, respectively. Acute and late toxicities were within acceptable limits. Conclusions: Locally advanced cervical cancer patients for whom intracavitary BT is unsuitable can achieve excellent LRC and OS with a combination of EBRT and HDR-ISBT.

    Purpose: To observe, by retrospective analysis, the curative effects and complications due to californium-252 ({sup 252}Cf) neutron intracavitary brachytherapy (ICBT) combined with external-beam radiotherapy (EBRT) in the treatment of cervical cancer. Methods and Materials: From February 1999 to December 2007, 696 patients with cervical cancer (Stages IB to IIIB) were treated with {sup 252}Cf-ICBT in combination of EBRT. Of all, 31 patients were at Stage IB, 104 at IIA, 363 at IIB, 64 at IIIA, and 134 at IIIB. Californium-252 ICBT was delivered at 7-12 Gy per insertion per week, with a total dose of 29-45 Gy to reference point A in three to five insertions. The whole pelvic cavity was treated with 8-MV X-ray external irradiation at 2 Gy per fraction, four times per week. After 16-38 Gy of external irradiation, the center of the whole pelvic field was blocked with a 4-cm-wide lead shield, with a total external irradiation dose of 44-56 Gy. The total treatment course was 5 to 6 weeks. Results: Overall survival rate at 3 and 5 years for all patients was 76.0% and 64.9%, respectively. Disease-free 3- and 5-year survival rates of patients were 71.2% and 58.4%, respectively. Late complications included vaginal contracture and adhesion, radiation proctitis, radiation cystitis, and inflammatory bowel, which accounted for 5.8%, 7.1%, 6.2%, and 4.9%, respectively. Univariate analysis results showed significant correlation of stage, age, histopathologic grade, and lymph node status with overall survival. Cox multiple regression analysis showed that the independent variables were stage, histopathologic grade, tumor size, and lymphatic metastasis in all patients. Conclusion: Results of this series suggest that the combined use of {sup 252}Cf-ICBT with EBRT is an effective method for treatment of cervical cancer.

    Purpose Dose-escalated (DE) radiotherapy in the setting of localized prostate cancer has been shown to improve biochemical disease-free survival (bDFS) in several studies. In the same group of patients, androgen deprivation therapy (ADT) has been shown to confer a survival benefit when combined with radiotherapy doses of up to 70 Gy; however, there is currently little long-term data on patients who have received high-dose intensity-modulated radiotherapy (IMRT) with ADT. We report the long-term outcomes in a large cohort of patients treated with the combination of DE image-guided IMRT (IG-IMRT) and ADT. Methods and materials Patients with localized prostate cancer were identified from a centralized database across an integrated cancer center. All patients received DE IG-IMRT, combined with ADT, and had a minimum follow up of 12 months post-radiotherapy. All relapse and toxicity data were collected prospectively. Actuarial bDFS, metastasis-free survival, prostate cancer-specific survival, and multivariate analyses were calculated using the SPSS v20.0 statistical package. Results Seven hundred and eighty-two eligible patients were identified with a median follow up of 46 months. Overall, 4.3% of patients relapsed, 2.0% developed distant metastases, and 0.6% died from metastatic prostate cancer. At 5-years, bDFS was 88%, metastasis-free survival was 95%, and prostate cancer-specific survival was 98%. Five-year grade 2 genitourinary and gastrointestinal toxicity was 2.1% and 3.4%, respectively. No grade 3 or 4 late toxicities were reported. Pretreatment prostate specific antigen (P=0.001) and Gleason score (P=0.03) were significant in predicting biochemical failure on multivariate analysis. Conclusion There is a high probability of tumor control with DE IG-IMRT combined with androgen deprivation, and this is a technique with a low probability of significant late toxicity. Our long term results corroborate the safety and efficacy of treating with IG-IMRT to high doses

    Purpose/Objective(s): Mature data on tumor control and survival are presented from a randomized trial of the addition of a brachytherapy boost to long-course neoadjuvant chemoradiation therapy (CRT) for locally advanced rectal cancer. Methods and Materials: Between March 2005 and November 2008, 248 patients with T3-4N0-2M0 rectal cancer were prospectively randomized to either long-course preoperative CRT (50.4 Gy in 28 fractions, per oral tegafur-uracil and L-leucovorin) alone or the same CRT schedule plus a brachytherapy boost (10 Gy in 2 fractions). The primary trial endpoint was pathologic complete response (pCR) at the time of surgery; secondary endpoints included overall survival (OS), progression-free survival (PFS), and freedom from locoregional failure. Results: Results for the primary endpoint have previously been reported. This analysis presents survival data for the 224 patients in the Danish part of the trial. In all, 221 patients (111 control arm, 110 brachytherapy boost arm) had data available for analysis, with a median follow-up time of 5.4 years. Despite a significant increase in tumor response at the time of surgery, no differences in 5-year OS (70.6% vs 63.6%, hazard ratio [HR] = 1.24, P=.34) and PFS (63.9% vs 52.0%, HR=1.22, P=.32) were observed. Freedom from locoregional failure at 5 years were 93.9% and 85.7% (HR=2.60, P=.06) in the standard and in the brachytherapy arms, respectively. There was no difference in the prevalence of stoma. Explorative analysis based on stratification for tumor regression grade and resection margin status indicated the presence of response migration. Conclusions: Despite increased pathologic tumor regression at the time of surgery, we observed no benefit on late outcome. Improved tumor regression does not necessarily lead to a relevant clinical benefit when the neoadjuvant treatment is followed by high-quality surgery.

    Purpose: To retrospectively review the results of a single-institution series of accelerated hypofractionated radiotherapy for early-stage non-small-cell lung cancer (NSCLC) in patients who are medically inoperable or who refuse surgery. Methods and Materials: Peripherally located T1 to T3 N0 M0 tumors were treated with 48 to 60 Gy in 12 to 15 fractions between 1996 and 2007. No elective nodal irradiation was delivered. Patient, tumor, and treatment information was abstracted from the medical records. Results: A total of 124 tumors were treated in 118 patients (56 male and 62 female). Median age at diagnosis was 76.3 years (range, 49-90 years). In all, 113 patients (95.8%) were not surgical candidates because of medical comorbidities. The 2- and 5-year overall survival (OS) rates were 51.0% and 23.3%, respectively, and the 2- and 5-year cause-specific survival (CSS) rates were 67.6% and 59.8%, respectively. The 2- and 5-year actuarial local control (LC) rates were 76.2% and 70.1%, respectively. Univariate analysis revealed that tumor size less than 3cm compared with greater than 3 cm resulted in significantly improved OS (40.0% vs. 5.0% at 5 years; p = 0.0002), CSS (69.7% vs. 45.1% at 5 years; p = 0.0461), and a trend toward better LC (82.5% vs. 66.9% at 2 years, 76.6% vs. 60.8% at 5 years; p = 0.0685). Treatment was well tolerated and there were no treatment delays because of acute toxicity. Conclusions: Accelerated hypofractionated radiotherapy with 48 to 60 Gy using fractions of 4 Gy per day provides very good results for small tumors in medically inoperable patients with early-stage NSCLC.

    Neither epidural (EDA) or intrathecal (IT) morphine nor EDA opiate + bupivacaine provides acceptable relief of some types of cancer pain, e.g. pain originating from mucocutaneous ulcers, deafferentation pain, continuous and intermittent visceral and ischaemic pain, and that occurring with body movement as a result of a fracture. To improve pain relief in such conditions, we gave combinations of morphine and bupivacaine through open IT-catheters to 52 patients with "refractory", severe (VAS 7-10 out of 10), complex cancer pain (Edmonton Stage-3), for periods of 1-305 (median = 23) days. The efficacy of the treatment was estimated from: 1) daily dosage (intraspinal and total opiates, and intraspinal bupivacaine), and 2) scores of non-opiate analgesic and sedative consumption, gait and daily activities, and amount and pattern of sleep. Forty-four patients obtained continuous and acceptable pain relief (VAS 0-2), 26 of them with daily doses of IT-bupivacaine of less than or equal to 30 mg/day (less than or equal to 1.5 mg/h). Higher IT-bupivacaine doses (greater than 60-305 mg/day), not always giving acceptable pain relief, were necessary in 13 patients with deafferentation pain from the spinal cord or brachial or lumbosacral plexuses or pain from the coeliac plexus, or from large, ulcerated mucocutaneous tumours. By combining IT-bupivacaine with IT-morphine, it was possible to use relatively low IT-morphine doses (10-25 mg/day during the first 2 months of treatment) in more than half of the patients. The IT-treatment significantly decreased the total (all routes) opiate consumption and significantly improved sleep, gait and daily activities. For the whole period of observation (6 months), the IT-treatment was assessed as adequate in 3.8%, good in 23.1%, very good in 59.6% and excellent in 13.5% of the cases. Adverse effects of the IT-bupivacaine (paraesthesiae, paresis, gait impairment, urinary retention, anal sphincter disturbances and orthostatic hypotension) did

    The purpose of this study was to assess the validity of CO2 laser cordectomy in the treatment of early glottic cancer and to determine the impact of margin status on disease-free survival and of the operation on voice quality. This is a retrospective review of 169 patients. Quantitative and qualitative variables were statistically compared. The impact on overall and disease-free survivals of different variables was calculated by univariate and multivariate analyses. Ten-year overall and disease free-survivals were 75 % and 60 %, respectively. Age and clinical stage showed a significant negative impact on overall survival, while margin status both on overall and disease-free survivals. The degree of dysphonia was directly related to the extension of the resection. This series confirms the good oncologic and functional outcomes of laser surgery for Tis, T1 and selected T2 glottic tumors. Patients with positive margins should undergo a further treatment or a very close follow-up. PMID:25895574

    With earlier cancer diagnosis among older patients with cancer, the possibility of curing cancer increases. However, cancer treatment may have a long-lasting impact on older cancer survivors. It is vital to screen, diagnose, and properly manage the long-term toxicities of cancer treatment in order to maintain the quality of life of older cancer survivors. PMID:26614861

    Purpose This article presents the long-term results of the international multicenter randomized trial that investigated the use of neoadjuvant cisplatin, methotrexate, and vinblastine (CMV) chemotherapy in patients with muscle-invasive urothelial cancer of the bladder treated by cystectomy and/or radiotherapy. Nine hundred seventy-six patients were recruited between 1989 and 1995, and median follow-up is now 8.0 years. Patients and Methods This was a randomized phase III trial of either no neoadjuvant chemotherapy or three cycles of CMV. Results The previously reported possible survival advantage of CMV is now statistically significant at the 5% level. Results show a statistically significant 16% reduction in the risk of death (hazard ratio, 0.84; 95% CI, 0.72 to 0.99; P = .037, corresponding to an increase in 10-year survival from 30% to 36%) after CMV. Conclusion We conclude that CMV chemotherapy improves outcome as first-line adjunctive treatment for invasive bladder cancer. Two large randomized trials (by the Medical Research Council/European Organisation for Research and Treatment of Cancer and Southwest Oncology Group) have confirmed a statistically significant and clinically relevant survival benefit, and neoadjuvant chemotherapy followed by definitive local therapy should be viewed as state of the art, as compared with cystectomy or radiotherapy alone, for deeply invasive bladder cancer.

    Purpose: To correlate tumor oxygenation status with long-term biochemical outcome after prostate brachytherapy. Methods and Materials: Custom-made Eppendorf PO{sub 2} microelectrodes were used to obtain PO{sub 2} measurements from the prostate (P), focused on positive biopsy locations, and normal muscle tissue (M), as a control. A total of 11,516 measurements were obtained in 57 men with localized prostate cancer immediately before prostate brachytherapy was given. The Eppendorf histograms provided the median PO{sub 2}, mean PO{sub 2}, and % <5 mm Hg or <10 mm Hg. Biochemical failure (BF) was defined using both the former American Society of Therapeutic Radiation Oncology (ASTRO) (three consecutive raises) and the current Phoenix (prostate-specific antigen nadir + 2 ng/mL) definitions. A Cox proportional hazards regression model evaluated the influence of hypoxia using the P/M mean PO{sub 2} ratio on BF. Results: With a median follow-up time of 8 years, 12 men had ASTRO BF and 8 had Phoenix BF. On multivariate analysis, P/M PO{sub 2} ratio <0.10 emerged as the only significant predictor of ASTRO BF (p = 0.043). Hormonal therapy (p = 0.015) and P/M PO{sub 2} ratio <0.10 (p = 0.046) emerged as the only independent predictors of the Phoenix BF. Kaplan-Meier freedom from BF for P/M ratio <0.10 vs. {>=}0.10 at 8 years for ASTRO BF was 46% vs. 78% (p = 0.03) and for the Phoenix BF was 66% vs. 83% (p = 0.02). Conclusions: Hypoxia in prostate cancer (low mean P/M PO{sub 2} ratio) significantly predicts for poor long-term biochemical outcome, suggesting that novel hypoxic strategies should be investigated.

    Purpose: To analyze long-term outcome and prognostic factors for high-risk prostate cancer defined by National Comprehensive Cancer Network criteria treated with high-dose radiotherapy and androgen deprivation in a single institution. Methods and Materials: A total of 306 patients treated between 1995 and 2007 in a radiation dose-escalation program fulfilled the National Comprehensive Cancer Network high-risk criteria. Median International Commission on Radiation Units and Measurements radiation dose was 78 Gy (range, 66.0-84.1 Gy). Long-term androgen deprivation (LTAD) was administered in 231 patients, short-term androgen deprivation (STAD) in 59 patients, and no hormones in 16 patients. The Phoenix (nadir plus 2 ng/mL) consensus definition was used for biochemical control. Multivariate analysis was performed to determine the independent prognostic impact of clinical and treatment factors. Median follow-up time was 64 months (range, 24-171 months). Results: The actuarial overall survival at 5 and 10 years was 95.7% and 89.8%, respectively, and the corresponding biochemical disease-free survival (bDFS) was 89.5% and 67.2%, respectively. Fourteen patients (4.6%) developed distant metastasis. Multivariate analysis showed that Gleason score >7 (p = 0.001), pretreatment prostate-specific antigen (PSA) level >20 ng/mL (p = 0.037), higher radiation dose (p = 0.005), and the use of adjuvant LTAD vs. STAD (p = 0.011) were independent prognostic factors affecting bDFS in high-risk disease. The 5-year bDFS for patients treated with LTAD plus radiotherapy dose >78 Gy was 97%. Conclusions: For high-risk patients the present series showed that the use of LTAD in conjunction with higher doses (>78 Gy) of radiotherapy was associated with improved biochemical tumor control. We observed that the presence of Gleason sum >7 and pretreatment PSA level >20 ng/mL in the same patient represents a 6.8 times higher risk of PSA failure. These men could be considered for clinical trials with

    Purpose: We present the long-term results of a cohort of patients with intermediate-risk prostate cancer (PC) treated with single-fraction high-dose-rate brachytherapy (HDRB) combined with hypofractionated external beam radiation therapy (HypoRT). Methods and Materials: Patients were treated exclusively with HDRB and HypoRT. HDRB delivered a dose of 10 Gy to the prostate surface and HypoRT consisted of 50 Gy delivered in 20 daily fractions. The first 121 consecutive patients with a minimum of 2 years posttreatment follow-up were assessed for toxicity and disease control. Results: The median follow-up was 65.2 months. No acute Grade III or higher toxicity was seen. Late Grade II gastrointestinal toxicity was seen in 9 patients (7.4%) and Grade III in 2 (1.6%). Late Grade III genitourinary toxicity was seen in 2 patients (1.6%). After a 24-month follow-up, a rebiopsy was offered to the first 58 consecutively treated patients, and 44 patients agreed with the procedure. Negative biopsies were found in 40 patients (91%). The 5-year biochemical relapse-free survival rate was 90.7% (95% CI, 84.5-96.9%), with 13 patients presenting biochemical failure. Among them, 9 were diagnosed with distant metastasis. Prostate cancer-specific and overall survival rates at 5 years were 100% and 98.8% (95% CI, 96.4-100%), respectively. Conclusion: The combination of HDRB and HypoRT is well tolerated, with acceptable toxicity rates. Furthermore, results from rebiopsies revealed an encouraging rate of local control. These results confirm that the use of conformal RT techniques, adapted to specific biological tumor characteristics, have the potential to improve the therapeutic ratio in intermediate-risk PC patients.

    Purpose: We have previously shown that the addition of cetuximab to chemoradiation therapy failed to improve complete response rates (pCR) in rectal cancer. Here we report the long-term results of the cetuximab added to preoperative radiation therapy with capecitabine and oxaliplatin (CET-CAPOX-RT) phase 1/2 study that evaluated preoperative chemoradiation with cetuximab, capecitabine, and oxaliplatin in patients with rectal cancer. Methods and Materials: The median follow-up was 63 months (range, 5-73 months). Sixty patients were enrolled; 3 patients were excluded due to protocol violation, and 4 died before surgery. Total mesorectal excision was performed in 53 patients, in 85% (n=45) with curative intention (M0-status). Secondary end points including overall survival (OS) disease-free survival (DFS) and cancer-specific survival (CSS) were calculated. The prognostic value of KRAS mutation status was also assessed. Results: Histopathological examination confirmed ypUICC stages 0 (n=4; pCR), I (n=17), II (n=10), III (n=14), and IV (n=8). For patients who underwent surgery (n=53), OS at 1, 3, and 5 years was 88.7%, 83%, and 75.5%, respectively, whereas CSS rates were 94.1%, 88.1%, and 78.1%, respectively. In the 45 patients who were treated with curative intent (M0), the OS rates at 1, 3, and 5 years were 91.1%, 88.9%, and 86.7%, respectively; whereas CSS rates were 97.6%, 95.2%, and 90.3%, respectively; and DFS rates were 90.7%, 88.3%, and 88.3%, respectively. We did not find any locoregional failure in patients with M0-status (n=45). Chronic toxicity was rare. KRAS mutations, as detected in 33.3%, showed no correlation with the clinicopathological parameters nor significance for either OS (P=.112), CSS (P=.264), or DFS (P=.565). Conclusions: Taken together, chemoradiation therapy combined with cetuximab is safe, feasible, and offers excellent survival rates. KRAS mutation status was not a predictive factor. Importantly, lack of improvement in pCR rate did not

    Purpose: To evaluate, in a Phase II trial conducted August 1998 through January 2001, the efficacy of neoadjuvant chemotherapy followed by chemoradiotherapy and definitive surgery in patients with locally advanced non-small-cell lung cancer (LA-NSCLC), Stages IIIA bulky and selected Stage IIIB. Patients and Methods: Staging of LA-NSCLC included computed tomography of cranium, thorax, and abdomen, whole-body positron emission tomography, and video mediastinoscopy. Induction chemotherapy with weekly paclitaxel and carboplatin was followed by hyperfractionated accelerated thoracic radiotherapy (45 Gy) with simultaneous weekly paclitaxel and carboplatin. Four to six weeks after completion of induction therapy, restaging and resection of primary tumor and lymph nodes was intended. Results: A total of 59 consecutive patients were enrolled, 25% with Stage IIIA bulky disease, 65% with Stage IIIB, and 10% with Stage IV (excluded from further analysis). Forty-one patients completed induction therapy; in 52.4% a functional (positron emission tomography) downstaging was proven. Thirty-two patients (59.3%) underwent complete tumor resection, and 5 patients had an exploratory thoracotomy only. Histopathologic downstaging was proven in 59.4% and complete response in 21.9%. Hospital mortality was 5.4%. Median duration of follow-up for living patients was 62.1 months. Overall median survival was 22.6 months, 58.2 months for completely resected patients. During induction chemotherapy, Grade 3/4 granulocytopenia occurred in 8% of patients; the most common Grade 3/4 toxicity of chemoradiation was esophagitis, in 26.4% of patients. Conclusions: Induction paclitaxel/carboplatin with hyperfractionated accelerated chemoradiotherapy followed by complete tumor resection demonstrates high efficacy in LA-NSCLC and offers a promising chance of long-term survival.

    In order to assess the effects of various cancer treatments on neuropsychological functioning, 74 long-term survivors of childhood cancer were examined. A comprehensive battery of tests was administered to two CNS treatment groups (irradiated and nonirradiated leukemia and lymphoma patients) and a control group (solid tumor and Hodgkin disease patients receiving no CNS treatment). The CNS-irradiated group obtained lower scores than the other two groups, with significant differences in visual-motor and fine motor skills, spatial memory, and arithmetic achievement resulting in significant differences in IQ scores (VIQ, PIQ, FSIQ). The results are discussed in relation to: (1) the effects of CNS irradiation on cognitive development; (2) the specificity of these effects; and (3) the relationship of age at diagnosis to treatment effects. It is concluded that although there is a general lowering of scores after CNS irradiation, the effect is most pronounced for nonlanguage skills. Age at diagnosis was less important than the type of treatment, with CNS irradiation reducing performance regardless of when cancer was diagnosed. There were indications that children with any type of cancer diagnosed before age 5 years are more likely to have some cognitive difficulties.

    Partial knee arthroplasty (PKA), either medial or lateral unicompartmental knee artroplasty (UKA) or patellofemoral arthroplasty (PFA) are a good option in suitable patients and have the advantages of reduced operative trauma, preservation of both cruciate ligaments and bone stock, and restoration of normal kinematics within the knee joint. However, questions remain concerning long-term survival. The goal of this review article was to present the long-term results of medial and lateral UKA, PFA and combined compartmental arthroplasty for multicompartmental disease. Medium- and long-term studies suggest reasonable outcomes at ten years with survival greater than 95% in UKA performed for medial osteoarthritis or osteonecrosis, and similarly for lateral UKA, particularly when fixed-bearing implants are used. Disappointing long-term outcomes have been observed with the first generation of patellofemoral implants, as well as early Bi-Uni (i.e., combined medial and lateral UKA) or Bicompartmental (combined UKA and PFA) implants due to design and fixation issues. Promising short- and med-term results with the newer generations of PFAs and bicompartmental arthroplasties will require long-term confirmation. PMID:26430081

    Background Spinal myxopapillary ependymomas (MPEs) are slowly growing ependymal gliomas with preferential manifestation in young adults. The aim of this study was to assess the outcome of patients with MPE treated with surgery, radiotherapy (RT), and/or chemotherapy. Methods The medical records of 183 MPE patients (male: 59%) treated at the MD Anderson Cancer Center and 11 institutions from the Rare Cancer Network were retrospectively reviewed. Mean patient' age at diagnosis was 35.5 ± 15.8 years. Ninety-seven (53.0%) patients underwent surgery without RT, and 86 (47.0%) were treated with surgery and/or RT. Median RT dose was 50.4 Gy. Median follow-up was 83.9 months. Results Fifteen (8.2%) patients died, 7 of unrelated cause. The estimated 10-year overall survival was 92.4% (95% CI: 87.7–97.1). Treatment failure was observed in 58 (31.7%) patients. Local failure, distant spinal relapse, and brain failure were observed in 49 (26.8%), 17 (9.3%), and 11 (6.0%) patients, respectively. The estimated 10-year progression-free survival was 61.2% (95% CI: 52.8–69.6). Age (<36 vs ≥36 y), treatment modality (surgery alone vs surgery and RT), and extent of surgery were prognostic factors for local control and progression-free survival on univariate and multivariate analysis. Conclusions In this series, treatment failure of MPE occurred in approximately one third of patients. The observed recurrence pattern of primary spinal MPE was mainly local, but a substantial number of patients failed nonlocally. Younger patients and those not treated initially with adjuvant RT or not undergoing gross total resection were significantly more likely to present with tumor recurrence/progression. PMID:25301811

    Proton pump inhibitors profoundly affect the stomach and have been associated with carcinoid tumors in female rats. There is now sufficient experience with this class of drugs to allow reasonable estimation of their safety in terms of cancer development. Long term proton pump inhibitor use is associated with an increase in gastric inflammation and development of atrophy among those with active Helicobacter pylori infections. The actual risk is unknown but is clearly low. However, it can be markedly reduced or eliminated by H. pylori eradication leading to the recommendation that patients considered for long term proton pump inhibitor therapy be tested for H. pylori infection and if present, it should be eradicated. Oxyntic cell hyperplasia, glandular dilatations, and fundic gland polyps may develop in H. pylori-uninfected patients, but these changes are believed to be reversible and without significant cancer risk.

    Background Physical activity is associated with reduced mortality and higher quality of life in breast cancer survivors; however, limited data on the prevalence of activity and long-term trends after diagnosis are available. Methods A multi-ethnic cohort of 631 women (18–64 years) with stage 0-IIIA breast cancer were followed for 10 years. Recreational aerobic activity (MET-hrs/week) was ascertained for the year before diagnosis (baseline), 24 months, 5 and 10 years after enrollment. Women were classified according to U.S. physical activity guidelines (≥150 mins/week moderate or ≥75 mins/week vigorous activity). The odds ratios (OR) for meeting guidelines at 5 and 10 years according to baseline factors was estimated using logistic regression. The change in MET-hrs/wk was predicted using linear regression. Results Pre-diagnosis, 34% of women met physical activity guidelines; 34.0%, 39.5%, and 21.4% met guidelines at 24 months, 5 years, and 10 years post-enrollment, respectively. Fewer than 8% of survivors met guidelines at all follow-up periods. Over 10 years, recreational aerobic activity decreased by a mean(SD) 4.3(16.2) MET-hrs/wk.. Meeting guidelines pre-diagnosis was strongly associated with meeting guidelines at 5 years [OR (95% CI): 2.76 (1.85–4.1)] and 10 years [OR (95% CI): 3.35 (2.13–5.28)]. No other demographic or prognostic factors were significantly associated with the 10-year change in MET-hrs/wk. Conclusion The vast majority of early breast cancer survivors do not meet national exercise recommendations 10 years post-diagnosis. Impact Physical activity levels are low in breast cancer survivors across the 10 years post-diagnosis, yet the predictors of activity in this population remain poorly understood. PMID:23576689

    Abstract Association between coffee consumption and gastric cancer risk remains controversial. Hence, we performed a meta-analysis to investigate and quantify the potential dose–response association between long-term coffee consumption and risk of gastric cancer. Pertinent studies were identified by searching PubMed and Embase from January 1996 through February 10, 2015 and by reviewing the reference lists of retrieved publications. Prospective cohort studies in which authors reported effect sizes and corresponding 95% confidence intervals (CIs) of gastric cancer for 3 or more categories of coffee consumption were eligible. Results from eligible studies were aggregated using a random effect model. All analyses were carried out using the STATA 12.0 software. Nine studies involving 15 independent prospective cohorts were finally included. A total of 2019 incident cases of gastric cancer were ascertained among 1,289,314 participants with mean follow-up periods ranging from 8 to 18 years. No nonlinear relationship of coffee consumption with gastric cancer risk was indentified (P for nonlinearity = 0.53; P for heterogeneity = 0.004). The linear regression model showed that the combined relative risk (RR) of every 3 cups/day increment of total coffee consumption was 1.07 (95% CI = 0.95–1.21). Compared with the lowest category of coffee consumption, the RR of gastric cancer was 1.18 (95% CI = 0.90–1.55) for the highest (median 6.5 cups/day) category, 1.06 (95% CI = 0.85–1.32) for the second highest category (median 3.5 cups/day), and 0.97 (95% CI = 0.79–1.20) for the third highest category (median 1.5 cups/day). Subgroup analysis showed an elevated risk in the US population (RR = 1.36, 95% CI = 1.06–1.75) and no adjustment for smoking (RR = 1.67, 95% CI = 1.08–2.59) for 6.5 cups/day. Current evidence indicated there was no nonlinear association between coffee consumption and gastric cancer risk. However, high

    AIM: To determine the long-term results of choledochodudenostomy in patients with benign billiary obstruction. METHODS: This prospective study was conducted at Sheri Kashmir Institute of Medical Sciences Srinagar Kashmir, India over a period of 10 years from January 1997 to December 2007. The total number of patients who underwent choledochoduodenostomy during this period was 270. On the basis of etiology of biliary tract obstruction, patients were divided into a calculus group, an oriental cholangiohepatitis group, a benign biliary stricture group and others. Patients were followed for a variable period of 13 mo to 15 years. RESULTS: Choledochoduodenostomy (CDD) with duo-denotomy was performend in four patients. CDD with removal of T- tube, CDD with left hepatic lobectomy and CDD with removal of intra biliary ruptured hydatid was performed in three patients each. In the remaining patients only CDD was performed. Immediate post operative complications were seen in 63 (23%) patients, while long-term complications were seen in 28 (11%) patients, which were statistically significant. Three patients died during hospitalization while four patients died in the late post-operative period. CONCLUSION: Our conclusion is that CDD is safe and produces good long term results when a permanent biliary drainage procedure is required. PMID:22408717

    The authors' objective was to evaluate the effectiveness of radical surgery with lymph node dissection for gallbladder carcinoma. Long-term results were analyzed in 40 patients in a 5-year study. The authors divided the 40 cases into two groups: 20 without positive nodes and 20 with positive nodes. In the group without positive nodes, one patient who underwent R1 resection died of a recurrence at 1 year 7 months. Seventeen of the 19 patients treated with R0 resection survived more than 5 years. The 5-year survival rate was 85% (17/20). In the group with positive nodes, 9 of the 13 patients treated with R0 resection survived more than 5 years, whereas the seven patients treated with R1 or R2 resection died within 5 years. The 5-year survival rate was 45% (9/20). Patients treated by R0 resection showed a 5-year survival rate of 69% (9/13). Thus we documented the favorable long-term results of radical surgery. R0 resection is a prerequisite for long-term survival. The results justify radical surgery with lymph node dissection. PMID:1359844

    The Wagner cone prosthesis is indicated in uncemented total hip replacement of cases with cylinder-shaped femurs, deformed femurs, femurs with increased antetorsion, and in conditions of intramedullary bony scar tissue after previous osteotomies. The objective of this study is to present long-term results. From January 1, 1993 to December 31, 1995, 132 implantations were made with the Wagner cone prosthesis. We report the clinical and radiographic results of 94 cone prostheses with a mean observation period of 11.5 years. The Merle d’Aubigné score improved from a preoperative mean value of 8.8 to a postoperative mean of 16.3. The radiographic evaluation revealed 32 cases with cortical hypertrophy, 73 cases with atrophy of the proximal femur, and 18 cases with complete pedestal formation. Radiolucencies over Gruen zones 1 and 7 occurred in 42 cases; only zone 1 was affected in 24 cases. Complications included three deep infections, three acetabular revisions, five total joint revisions, one recurrent luxation, and three heterotopic ossifications. In spite of the fact that the examined cohort often included patients who had undergone multiple previous operations (a maximum of six) of the proximal femur or the acetabulum, the long-term results of the Wagner cone prostheses were very promising.

    We evaluated the long-term results of recanalization with primary stenting for patients with long and complex iliac artery occlusions. This was a retrospective nonrandomised study. Between 1995 and 1999, 138 patients underwent recanalization of an occluded iliac artery with subsequent stenting. Patency results were calculated using Kaplan-Meier analysis. The mean length of follow-up was 108 months. Variables affecting primary stent patency such as patient age; stent type and diameter; lesion site, shape, and length; Society of Cardiovascular and Interventional Radiology classification; total runoff score; Fontaine classification; and cardiovascular risk factors were analysed using Breslow test. These variables were then evaluated for their relation to stent patency using Cox proportional hazards test. Technical success was 99%. Primary patency rates were 90% (SE .024), 85% (SE .029), 80% (SE .034), and 68% (SE .052) at 3, 5, 7, and 10 years, respectively. Lesion site (p = 0.022) and stent diameter (p = 0.028) were shown to have a statistically significant influence on primary stent patency. Long-term results of iliac recanalization and stent placement were excellent, without major complications, even in highly complex vascular obstructions. A primary endovascular approach appears to be justified in the majority of patients as a less invasive alternative treatment to surgery. In any case, a first-line interventional approach should be considered in elderly patients or in patients with severe comorbidities.

    Combined sialendoscopic and transcutaneous approach in parotid sialolithiasis is a surgical option for large and impacted stones. The aim of this study is to assess the long-term results regarding postoperative stenosis, recurrent swellings and gland function. Prospective study in a tertiary referral center of patients with parotid sialolithiasis requiring combined approach. A total of 12 patients have been treated within a period of 3 years. Intraductal stents were placed in 9 of 12 cases. Scintigraphic evaluation of salivary glands and follow-up sialendoscopy performed 1 year postoperatively. In total, fourteen stones (two stones in two cases) were successfully removed along with two coexisted inflammatory polyps. Postoperative endoscopic evaluation revealed mild stenosis in 7 out of 12 cases without clinical significance as no recurrent swellings were reported. Scintigraphy showed normal gland function in 11 cases and mild hypofunction in 1 case with long-standing history of sialolithiasis. All patients were free of symptoms within the follow-up period of time (median follow-up 15.5 months). Combined approach is a safe, gland preserving and efficacious procedure in long term. The stenosis in the area of ductal surgical opening when present does not seem to be of clinical value. PMID:25388993

    Background and Objectives Hospitals with high complex oncologic surgical volume have improved short-term outcomes. However, for long-term outcomes, the influence of other therapies must be considered. We compared effects of resection with other therapies on long-term outcomes across U.S. hospitals. Methods We examined claims in the Surveillance, Epidemiology, and End Results (SEER)-Medicare dataset for patients with esophageal (EC) and pancreatic (PC) cancers between 2005–2009, with follow-up through 2011, performing multivariable Cox proportional hazards analyses. We stratified hospitals by volume and compared rates of treatments in the context of survival. Results We studied 905 EC and 3,293 PC patients at 138 and 375 hospitals, respectively. For EC, resection rates were significantly higher (32.9% vs. 9.5%, P<0.001) in the highest versus lowest volume hospitals. Adjusted survival was also statistically significantly better (48.5% vs. 43.1%, P<0.001). For PC, resection rates were also statistically significantly higher (30.1% vs. 12.0%, P<0.001) with higher adjusted survival (21.5% vs. 19.9%, P = 0.01). We did not find variation in rates of other cancer treatments across hospitals. Conclusions A significant association exists between long-term survival and rates of cancer-directed surgery across hospitals, without variation in rates of other therapies. Access to resection appears to be key to reducing variation in long-term survival. PMID:26953166

    Lung cancer is the leading cause of cancer death in women, accompanied by greater psychological distress than other cancers. There is minimal but increasing awareness of the impact of lung cancer stigma (LCS) on patient outcomes. LCS is associated with increased symptom burden and decreased quality of life. The purpose of this study was to explore the experience of female long term lung cancer survivors in the context of LCS and examine how participants discursively adhere to or reject stigmatizing beliefs. Findings situated within Cataldo et al.’s theoretical model include: 1) addiction and tobacco marketing as possible precursors for LCS, 2) the possible role of expert providers as LCS enhancers, 3) response of overlapping complicated identity shifts, 4) simultaneous rejection and assumption of LCS, and 5) information control via advocacy activities as a LCS mitigation response. These findings expand the current understanding of LCS, and call for future conceptual exploration and theoretical revision, particularly with respect to the possibility of interaction between relevant related stigma(s) and LCS. As the number of women living with lung cancer increases, with longer survival times, the effect of LCS and other experiences of discrimination on patient outcomes could be substantial.

    In a series of 70 Wistar rats submitted to a noncontact diode laser-assisted carotid end-to-end anastomosis (LAMA) versus controlateral manual suture microanastomosis (CMA), contrast angiography and scanning electron microscopy were performed in a group of 18 animals at a long-term follow up to 7 months after operation. The investigation of angiography realized by means of a CGR General Electric DG 200 with a 512 digital matrix gave precise images of vessel wall repair and vessel patency. It permitted a simultaneous comparison between laser and manual anastomosis. Patency rate was 83% in LAMA and 78% in CMA. Nonlethal complications such as 1 stenosis, 2 thromboses in LAMA and 1 stenosis, 2 thromboses, and 1 pseudoaneurysm in CMA were observed. The results could be correlated to scanning electron microscopy findings and confirmed the morphological superiority of the laser technique.

    From 2001 to 2012, arterial reconstruction was performed in 306 out of 497 limbs (62%) with critical limb ischemia. The reasons for non-vascularization include high operative risk (36%), extended necrosis or infection (20%), and technical issues (15%). Cumulative patency and limb salvage in collagen disease were significantly worse compared to arteriosclerosis obliterans. Cumulative limb salvage, amputation free survival (AFS), and major adverse limb event and perioperative death (MALE + POD) in patients with end-stage renal disease (ESRD) were significantly worse compared to patients without ESRD, but not significant with regards to graft patency. Our finding suggests that aggressive arterial reconstruction provides satisfactory long-term results in critical limb ischemia so long as case selection for revascularization is properly made.

    The aim of our study was to assess long-term results of radiofrequency volumetric tissue reduction of inferior turbinates (RVTR). We performed a prospective long-term longitudinal evaluation of 305 patients affected by rhinitis (114 allergic and 191 non-allergic) who were unresponsive to medical treatment and underwent RVTR (January 2004 - December 2010). Subjects were followed for a mean period of 39.70 ± 19.41 months (range 24-60). Patients completed the NOSE-scale questionnaire pre- and post-operatively after 1 month and yearly for 5-years. Recurrence was assumed if the post-operative total NOSE score increased by at least 75% during follow-up and the patient restarted medical treatments. Estimation of relapse over time was performed by Kaplan-Meyer analyses. We documented overall good satisfaction of patients regarding the procedure, with a good rate of pain control and a low rate of complications. Post-operatively there was a significant improvement in nasal stuffiness, nasal obstruction and mouth breathing (p < 0.05). We observed a worsening trend for symptoms after 36 months with progressive increasing rate of recurrences that were significantly higher in allergic than non-allergic patients (p < 0.05). We also observed a slight worsening trend of global satisfaction of patients. Our study confirms the minor discomfort and low risk of side effects of RVTR. Our data showed good efficacy of the procedure in the majority of patients for at least 36 months after surgery, and in fact in this time period the cumulative probability to remain relapse-free was up to 0.8. In the following 2 years, we observed a worse temporal trend in term of recurrence rate, and in particular in allergic patients with a significant difference vs non-allergic individuals (p < 0.05).

    Purpose: To update 5-year results of a previously published study on special 7-days-a-week fractionation continuous accelerated irradiation (CAIR) for head-and-neck cancer patients. Methods and Materials: One hundred patients with squamous cell carcinoma of head and neck in Stage T{sub 2-4}N{sub 0-1}M were randomized between two definitive radiation treatments: accelerated fractionation 7 days a week including weekends (CAIR) and conventional 5 days a week (control). Hence the overall treatment time was 2 weeks shorter in CAIR. Results: Five-year local tumor control was 75% in the CAIR group and 33% in the control arm (p < 0.00004). Tumor-cure benefit corresponded with significant improvement in disease-free survival and overall survival rates. Confluent mucositis was the main acute toxicity, with the incidence significantly higher in CAIR patients than in control (respectively, 94% vs. 53%). When 2.0-Gy fractions were used, radiation necrosis developed in 5 patients (22%) in the CAIR group as a consequential late effect (CLE), but when fraction size was reduced to 1.8 Gy no more CLE occurred. Actuarial 5-year morbidity-free survival rate was similar for both treatments. Conclusions: Selected head-and-neck cancer patients could be treated very effectively with 7-days-a-week radiation schedule with no compromise of total dose and with slight 10% reduction of fraction dose (2 Gy-1.8 Gy), which article gives 1 week reduction of overall treatment time compared with standard 70 Gy in 35 fractions over 47-49 days. Although this report is based on the relatively small group of patients, its results have encouraged us to use CAIR fractionation in a standard radiation treatment for moderately advanced head-and-neck cancer patients.

    Purpose: Preoperative chemoradiotherapy (CRT) for locally advanced rectal cancer has shown benefit over postoperative CRT; however, a standard CRT regimen has yet to be defined. We performed a prospective concurrent CRT Phase II study with irinotecan and capecitabine in patients with locally advanced rectal cancer to investigate the efficacy and safety of this regimen. Methods and Materials: Patients with locally advanced, nonmetastatic, and mid-to-lower rectal cancer were enrolled. Radiotherapy was delivered in 1.8-Gy daily fractions for a total of 45 Gy in 25 fractions, followed by a coned-down boost of 5.4 Gy in 3 fractions. Concurrent chemotherapy consisted of 40 mg/m{sup 2} of irinotecan per week for 5 consecutive weeks and 1,650 mg/m{sup 2} of capecitabine per day for 5 days per week (weekdays only) from the first day of radiotherapy. Total mesorectal excision was performed within 6 {+-} 2 weeks. The pathologic responses and survival outcomes were included for the study endpoints. Results: In total, 48 patients were enrolled; 33 (68.7%) were men and 15 (31.3%) were women, and the median age was 59 years (range, 32-72 years). The pathologic complete response rate was 25.0% (11 of 44; 95% confidence interval, 12.2-37.8) and 8 patients (18.2% [8 of 44]) showed near-total tumor regression. The 5-year disease-free and overall survival rates were 75.0% and 93.6%, respectively. Grade 3 toxicities included leukopenia (3 [6.3%]), neutropenia (1 [2.1%]), infection (1 [2.1%]), alanine aminotransferase elevation (1 [2.1%]), and diarrhea (1 [2.1%]). There was no Grade 4 toxicity or treatment-related death. Conclusions: Preoperative CRT with irinotecan and capecitabine with treatment-free weekends showed very mild toxicity profiles and promising results in terms of survival.

    Purpose: To report late gastrointestinal (GI) and genitourinary (GU) toxicity, biochemical and clinical outcomes, and overall survival after hypofractionated radiation therapy for prostate cancer (PC). Methods and Materials: Three institutions included 113 patients with T1 to T3N0M0 PC in a phase II study. Patients were treated with 56 Gy in 16 fractions over 4 weeks. Late toxicity was scored using Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer criteria extended with additional symptoms. Biochemical outcome was reported according to the Phoenix definition for biochemical failure. Results: The incidence of late GI and GU toxicity was low. The 3-year actuarial risk of developing late GU and GI toxicity of grade {>=}2 was 13% and 8% respectively. Five-year biochemical non-evidence of disease (bNED) was 94%. Risk group, T stage, and deviation from planned hormone treatment were significant predictive factors for bNED. Deviation from hormone treatment remained significant in multivariate analysis. Five-year clinical non evidence of disease and overall survival was 95% and 91% respectively. No patient died from PC. Conclusions: Hypofractionated high-dose radiation therapy is a valuable treatment option for patients with PC, with excellent biochemical and clinical outcome and low toxicity.

    Purpose: To evaluate the long-term outcome and morbidity after intensified treatment for locally advanced head-and-neck cancer. Methods and Materials: Between May 2003 and December 2007, 77 patients with Stage III to IV head-and-neck cancer were treated with curative intent. Treatment consisted of accelerated radiotherapy to a dose of 68 Gy and concurrent cisplatin. Long-term survivors were invited to a multidisciplinary outpatient clinic for a comprehensive assessment of late morbidity with special emphasis on dysphagia, including radiological evaluation of swallowing function in all patients. Results: Compliance with the treatment protocol was high, with 87% of the patients receiving at least five cycles of cisplatin and all but 1 patient completing the radiotherapy as planned. The 5-year actuarial disease-free survival and overall survival rates were 40% and 47%, respectively. Locoregional recurrence-free survival at 5 years was 61%. The 5-year actuarial rates of overall late Radiation Therapy Oncology Group (RTOG)/European Organization for Research and Treatment of Cancer (EORTC) Grade 3 and Grade 4 toxicity were 52% and 25% respectively. Radiologic evaluation after a median follow-up of 44 months demonstrated impaired swallowing in 57% of the patients, including 23% with silent aspiration. Subjective assessment using a systematic scoring system indicated normalcy of diet in only 15.6% of the patients. Conclusion: This regimen of accelerated radiotherapy with weekly cisplatin produced favorable tumor control rates and survival rates while compliance was high. However, comprehensive assessment by a multidisciplinary team of medical and paramedical specialists revealed significant long-term morbidity in the majority of the patients, with dysphagia being a major concern.

    longer-term (approximately 25-day) full-scale tests on two different units. The longer-term tests were conducted to confirm the effectiveness of the sorbents tested over extended operation on two different boilers, and to determine balance-of-plant impacts. The first long-term test was conducted on FirstEnergy's BMP, Unit 3, and the second test was conducted on AEP's Gavin Plant, Unit 1. The Gavin Plant testing provided an opportunity to evaluate the effects of sorbent injected into the furnace on SO{sub 3} formed across an operating SCR reactor. This report presents the results from those long-term tests. The tests determined the effectiveness of injecting commercially available magnesium hydroxide slurry (Gavin Plant) and byproduct magnesium hydroxide slurry (both Gavin Plant and BMP) for sulfuric acid control. The results show that injecting either slurry could achieve up to 70 to 75% overall sulfuric acid removal. At BMP, this overall removal was limited by the need to maintain acceptable electrostatic precipitator (ESP) particulate control performance. At Gavin Plant, the overall sulfuric acid removal was limited because the furnace injected sorbent was less effective at removing SO{sub 3} formed across the SCR system installed on the unit for NOX control than at removing SO{sub 3} formed in the furnace. The long-term tests also determined balance-of-plant impacts from slurry injection during the two tests. These include impacts on boiler back-end temperatures and pressure drops, SCR catalyst properties, ESP performance, removal of other flue gas species, and flue gas opacity. For the most part the balance-of-plant impacts were neutral to positive, although adverse effects on ESP performance became an issue during the BMP test.

    Objective Radiation therapy (RT) for esophageal cancer often results in unintended radiation doses delivered to the heart owing to anatomic proximity. Using the Surveillance, Epidemiology, and End Results (SEER) database, we examined late cardiac death in survivors of esophageal cancer that had or had not received RT. Methods 5,630 patients were identified that were diagnosed with esophageal squamous cell carcinoma (SCC) or adenocarcinoma (AC) from 1973–2012, who were followed for at least 5 years after therapy. Examined risk factors for cardiac death included age (≤55/56-65/66-75/>75), gender, race (white/non-white), stage (local/regional/distant), histology (SCC/AC), esophageal location (<18cm/18-24cm/25-32cm/33-40cm from incisors), diagnosis year (1973-1992/1993-2002/2003-2012), and receipt of surgery and/or RT. Time to cardiac death was evaluated using the Kaplan-Meier method. A Cox model was used to evaluate risk factors for cardiac death in propensity score matched data. Results Patients who received RT were younger, diagnosed more recently, had more advanced disease, SCC histology, and no surgery. The RT group had higher risk of cardiac death than the no-RT group (log-rank p<0.0001). The median time to cardiac death in the RT group was 289 months (95% CI, 255–367) and was not reached in the no-RT group. The probability of cardiac death increased with age and decreased with diagnosis year, and this trend was more pronounced in the RT group. Multivariate analysis found RT to be associated with higher probability of cardiac death (OR 1.23, 95% CI 1.03–1.47, HR 1.961, 95% CI 1.466–2.624). Lower esophageal subsite (33–40 cm) was also associated with a higher risk of cardiac death. Other variables were not associated with cardiac death. Conclusions Recognizing the limitations of a SEER analysis including lack of comorbidity accountability, these data should prompt more definitive study as to whether a possible associative effect of RT on cardiac death

    Various techniques and materials have been proposed to deal with the problems that concern radical cavities, such as recurrence of the inflammatory process, the need for regular medication, and social inconvenience (eg, inability to practice water sports, working in an adverse enviroment). This article provides a detailed report of the results of revalidation of old radical cavities using hydroxyapatite granules as a filling. The material was incorporated with fibrin adhesive to fill the mastoid cavity and was covered with a sheet of bone pate sealant. Twenty-eight patients with chronic discharging old radical cavities were selected for this study (mean follow-up 11.4 years; range 10-14 years). At the 6-month follow-up, grafting was successful in 25 patients, whereas the functional outcomes showed an air-bone gap below 30 dB in 18 patients. No postoperative sensorineural hearing loss was observed. The long-term follow-up demonstrated a slight worsening of the initial findings; four other patients had reperforation of the tympanic membrane, and hearing deteriorated in five patients to above 30 dB air-bone gap. These results could be a consequence of an alteration in the function of the eustachian tube and of the severity of the preoperative pathologic processes. PMID:15841992

    The purpose of this work was to determine the risk of local-regional failure following post-mastectomy radiotherapy and the incidence of complications associated with such treatment. The authors retrospectively analyzed the results in 309 patients with Stage I--III invasive breast cancer treated with post-mastectomy radiation therapy between 1975 and 1985. The median radiotherapy dose was 45 Gy in 1.8 to 2.25 Gy fractions. One hundred forty-seven (48%) of the patients received adjuvant systemic chemotherapy with 115 (78%) of these receiving a CMF-based or doxorubicin-containing regime. The median follow-up time of surviving patients was 130 months (range, 28 to 191 months) after mastectomy. Seventeen patients (6%) developed a local-regional failure at an interval of 4 to 87 months after radiotherapy. Moderate or severe complications related to radiotherapy and requiring treatment were uncommon. Symptomatic radiation pneumonitis occurred in four patients (1.3%), arm edema in 18 (5.8%), and brachial plexopathy in 2 (0.6%). The authors conclude that post-operative radiotherapy is a safe and effective means of reducing local-regional failure following mastectomy. The efficacy of post-mastectomy radiotherapy in improving survival should be addressed in new large randomized controlled studies. 33 refs., 1 fig., 3 tabs.

    Purpose: To report the long-term survival and toxicity of a multi-institutional phase 2 study of concurrent chemoradiation therapy (CCRT) for locally advanced cervical cancer in east and southeast Asia. Methods and Materials: Ten institutions from 8 Asian countries participated in the study. Between April 2003 and March 2006, 120 patients (60 with bulky stage IIB and 60 with stage IIIB) were treated with CCRT. Radiation therapy consisted of pelvic external beam radiation therapy and either high-dose-rate or low-dose-rate intracavitary brachytherapy. Five cycles of weekly cisplatin (40 mg/m{sup 2}) were administered during the course of radiation therapy. Treatment results were evaluated by the rates of local control, overall survival, and late toxicities. Results: Median follow-up was 63.7 months, and the follow-up rate at 5 years was 98%. The 5-year local control and overall survival rates for all patients were 76.8% and 55.1%, respectively. The 5-year rates of major late toxicities of the rectum and bladder were 7.9% and 0%, respectively. Conclusions: The long-term results have suggested that CCRT is safe and effective for patients with locally advanced cervical cancer in east and southeast Asia. However, further efforts are needed to improve overall survival.

    Purpose: This prospective, phase 2 study aimed at assessing the efficacy of accelerated fractionation radiation therapy by concomitant boosts (CBs) associated with chemoradiation therapy (CRT) of the whole pelvis, in improving the rate of pathological complete response (pCR) to treatment in patients with International Federation of Gynaecology and Obstetrics (FIGO) stage IB2-IVA locally advanced cervical cancer. Methods and Materials: Neoadjuvant CRT included conformal irradiation of the whole pelvis with a total dose of 39.6 Gy (1.8 cGy/fraction, 22 fractions), plus additional irradiation of primary tumor and parametria with 10.8 Gy administered with CBs (0.9 cGy/fraction, 12 fractions, every other day). Concomitant chemotherapy included cisplatin (20 mg/m{sup 2}, days 1-4 and 26-30 of treatment), and capecitabine (1300 mg/m{sup 2}/daily, orally) during the first 2 and the last 2 weeks of treatment. Radical hysterectomy plus pelvic with or without aortic lymphadenectomy was performed within 6 to 8 weeks from CRT. Toxicity was recorded according to Radiation Therapy Oncology Group toxicity criteria and Chassagne grading system. Based on the Simon design, 103 cases were required, and the regimen would be considered active if >45 pCR were registered (α error = 0.05; β error = 0.1). Results: pCR was documented in 51 cases (50.5%), and the regimen was considered active, according to the planned statistical assumptions. At median follow-up of 36 months (range: 7-85 months), the 3-year local failure rate was 7%, whereas the 3-year disease-free and overall survival rates were 73.0% and 86.1%, respectively. Grade 3 leukopenia and neutropenia were reported in only 1 and 2 cases, respectively. Gastrointestinal toxicity was always grade 1 or 2. Conclusions: Addition of CBs in the accelerated fractionation modality to the whole pelvis chemoradiation followed by radical surgery results in a high rate of pathologically assessed complete response to CRT and a very

    The clinical material consists of 217 patients with squamous cell carcinoma in supraglottic and glottic larynx in clinical stage T1-3N0M0 irradiated radically in Warsaw Oncology Centre in 1995-1998. All patients were treated with Co-60, according to two schedules of fractionation, with maintenance of the consistent therapeutic protocol. The same team of doctors worked on the treatment of patients and on the follow-up as well. The clinical material is a part of a three-phased clinical trial KBN 0295. In the course of observation, the progression of cancer was not observed in 157 patients, among whom, 66% were treated conventionally and 79% with accelerated fractionation method. 60 cases of loco-regional recurrences were noted, among which 55 were regional. The majority of failure cases was observed until the 30(th) of the month after the radiotherapy ended. In conventional fractionation treatment, recurrences in T1 were 8/31 (26%), in T2 22/59 (37%) and in T3 8/20 (40%). In patients treated with AF, recurrences were T1 5/39 (13%), T2 15/55 (27%) and T3 2/13 (15%) respectively. The percentage of primary site tumour recurrences for each localization and kind of treatment was analysed. In CF 28/78 (37%) of glottic tumour recurrences and 10/34 (29%) of supraglottic tumour, recurrences were observed. In AF, 12/71 (17%) and 10/36 (28%) were observed respectively. In 48 cases salvage surgery was used, and 12 patients were not qualified because of tumour massive progression or because they refused to have a surgery. Among 34 cases (16%) of the second primary tumour or distant methastases, 25 were observed with glottic cancer, among which 23 were observed in early stages, and 9 cases with supraglottic cancer, among which, 6 showed early stage of tumour. In only 3 cases out of all the patients, distant methastases were confirmed in histopatology examination. The main cause of failure in larynx cancer patients in stage T1 is that 3N0M0 are local recurrences. Second primary or

    Objectives: High-dose external radiation for localized prostate cancer results in favorable clinical outcomes and low toxicity rates. Here, we report long-term quality of life (QOL) outcome for men treated with conformal protons. Methods: QOL questionnaires were sent at specified intervals to 95 men who received proton radiation. Of these, 87 men reported 3- and/or 12-month outcomes, whereas 73 also reported long-term outcomes (minimum 2 years). Symptom scores were calculated at baseline, 3 months, 12 months, and long-term follow-up. Generalized estimating equation models were constructed to assess longitudinal outcomes while accounting for correlation among repeated measures in an individual patient. Men were stratified into functional groups from their baseline questionnaires (normal, intermediate, or poor function) for each symptom domain. Long-term QOL changes were assessed overall and within functional groups using the Wilcoxon signed-rank test. Results: Statistically significant changes in all four symptom scores were observed in the longitudinal analysis. For the 73 men reporting long-term outcomes, there were significant change scores for incontinence (ID), bowel (BD) and sexual dysfunction (SD), but not obstructive/irritative voiding dysfunction (OID). When stratified by baseline functional category, only men with normal function had increased scores for ID and BD. For SD, there were significant changes in men with both normal and intermediate function, but not poor function. Conclusions: Patient reported outcomes are sensitive indicators of treatment-related morbidity. These results quantitate the long-term consequences of proton monotherapy for prostate cancer. Analysis by baseline functional category provides an individualized prediction of long-term QOL scores. High dose proton radiation was associated with small increases in bowel dysfunction and incontinence, with more pronounced changes in sexual dysfunction.

    NASA’s Heliophysics Data Management Policy calls for discipline-specific “final archives,” which will be responsible for the long-term archiving and service of Heliophysics mission data. Long-term archival functions, such as periodic revalidation of the data and migration to newer storage media when appropriate, have never been part of the Solar Data Analysis Center core capabilities. We also recognize that the largest space solar physics data set, the SDO AIA and HMI data at the Stanford Joint Science and Operations Center (JSOC), will eventually need preservation and long-term access, as will the potentially much larger data archive of DKIST observations. We have carried out a study of data archiving best practices in other disciplines and organizations, including NASA’s Space Physics Data Facility (SPDF), the National Institute of Standards and Technology (NIST), and private industry, and report on the lessons learned and possible cost models. We seek input from the broader solar physics community on the relative value of various levels of preservation effort.

    The Subsurface Disposal Area (SDA) of the Radioactive Waste Management Complex (RWMC) located at the Idaho National Engineering and Environmental Laboratory (INEEL) contains neutron-activated metals from non-fuel, nuclear reactor core components. The Long-Term Corrosion/Degradation (LTCD) Test is designed to obtain site-specific corrosion rates to support efforts to more accurately estimate the transfer of activated elements to the environment. The test is using two proven, industry-standard methods—direct corrosion testing using metal coupons, and monitored corrosion testing using electrical/resistance probes—to determine corrosion rates for various metal alloys generally representing the metals of interest buried at the SDA, including Type 304L stainless steel, Type 316L stainless steel, Inconel 718, Beryllium S200F, Aluminum 6061, Zircaloy-4, low-carbon steel, and Ferralium 255. In the direct testing, metal coupons are retrieved for corrosion evaluation after having been buried in SDA backfill soil and exposed to natural SDA environmental conditions for times ranging from one year to as many as 32 years, depending on research needs and funding availability. In the monitored testing, electrical/resistance probes buried in SDA backfill soil will provide corrosion data for the duration of the test or until the probes fail. This report provides an update describing the current status of the test and documents results to date. Data from the one-year and three-year results are also included, for comparison and evaluation of trends. In the six-year results, most metals being tested showed extremely low measurable rates of general corrosion. For Type 304L stainless steel, Type 316L stainless steel, Inconel 718, and Ferralium 255, corrosion rates fell in the range of “no reportable” to 0.0002 mils per year (MPY). Corrosion rates for Zircaloy-4 ranged from no measurable corrosion to 0.0001 MPY. These rates are two orders of magnitude lower than those specified in

    The Children’s Cancer Group enrolled 13,298 young people age < 21 years on one of 16 protocols between 1983 and 2002. Outcomes were examined in three time periods, 1983–1988, 1989–1995, 1996–2002. Over the three intervals, 10-year event-free survival (EFS) for Rome/NCI standard risk and higher risk B-precursor patients was 68% and 58%, 77% and 63%, and 78% and 67%, respectively; while for standard risk and higher risk T-cell patients, EFS was 65% and 56%, 78% and 68%, and 70% and 72%, respectively. Five-year EFS for infants was 36%, 38%, and 43%, respectively. Seminal randomized studies led to a number of important findings. Stronger post induction intensification improved outcome for both standard and higher risk patients. With improved systemic therapy, additional IT methotrexate effectively replaced cranial radiation. For standard risk patients receiving three-drug induction, iso-toxic substitution of dexamethasone for prednisone improved EFS. Pegylated asparaginase safely and effectively replaced native asparaginase. Thus, rational therapy modifications yielded better outcomes for both standard and higher risk patients. These trials provide the platforms for current Children’s Oncology Group trials. PMID:20016531

    Cognitive decline is a common health problem among breast cancer patients and understanding trajectories of cognitive change following among breast cancer survivors is an important public health goal. We conducted a longitudinal study to investigate the cognitive function changes from 18 month to 3 years after breast cancer diagnosis among participants of the Shanghai Breast cancer survivor study, a population-based cohort study of breast cancer survivors. In our study, we completed cognitive function evaluation for 1,300 breast cancer survivors at the 18th month’s survey and 1,059 at 36th month’s survey, respectively, using a battery of cognitive function measurements. We found the scores in attention and executive function, immediate memory and delayed memory significantly improved from 18 to 36 months after breast cancer diagnosis. The improvements appeared in breast cancer survivors receiving treatments (i.e., surgery, radiotherapy, tamoxifen, or chemotherapy combined with or without tamoxifen), but not in those who received neither chemotherapy nor tamoxifen treatment. The results indicate that cognitive functions, particularly immediate verbal episodic memory, and delayed memory significantly improved among breast cancer survivors from 18 to 36 months after cancer diagnosis. In general, comorbidity was inversely associated with the improvements. PMID:25005574

    Syndesmotic disruption occurs in more than 10% of ankle fractures. Operative treatment with syndesmosis screw fixation has been successfully performed for decades and is considered the gold standard of treatment. Few studies have reported the long-term outcomes of syndesmosis injuries. This study investigated long-term patient-reported, radiographic, and functional outcomes of syndesmosis injuries treated with screw fixation and subsequent timed screw removal. A retrospective cohort study was carried out at a Level I trauma center. The study group included 43 patients who were treated for ankle fractures with associated syndesmotic disruptions between December 2001 and May 2011. The study included case file reviews, self-reported questionnaires, radiologic reviews, and clinical assessments. At 5.1 (±1.76) years after injury, 60% of participants had pain, 26% had degenerative changes, 51% had loss of tibiofibular overlap, and 33% showed medial clear space widening. Retained syndesmotic positions on radiographs were linked to better self-reported outcomes. There is an inversely proportional relation between age at the time of injury and satisfaction with the outcome of the ankle fracture as well as a directly proportional relation between age at the time of injury and pain compared with the preinjury state. Optimal restoration and preservation of the syndesmosis is crucial. Syndesmotic disruption is associated with poor long-term outcomes after ankle fracture. Greater age is a risk factor for chronic pain and dissatisfaction with the outcome of ankle fracture and syndesmosis injury. Therefore, patient education to facilitate realistic expectations about recovery is vital, especially in older patients. PMID:26558664

    Purpose: The aim of this study was to evaluate the effectiveness of low-dose-rate brachytherapy for local control and relapse-free survival in squamous cell and basal cell carcinomas of the lips. We compared two groups: one with tumors on the skin and the other with tumors on the lip. Patients and methods: All patients had been treated at Claudius Regaud Cancer Centre from 1990 to 2008 for squamous cell or basal cell carcinoma. Low-dose-rate brachytherapy was performed with iridium 192 wires according to the Paris system rules. On average, the dose delivered was 65 Gy. Results: 172 consecutive patients were included in our study; 69 had skin carcinoma (squamous cell or basal cell), and 92 had squamous cell mucosal carcinoma. The average follow-up time was 5.4 years. In the skin cancer group, there were five local recurrences and one lymph node recurrence. In the mucosal cancer group, there were ten local recurrences and five lymph node recurrences. The 8-year relapse-free survival for the entire population was 80%. The 8-year relapse-free survival was 85% for skin carcinoma 75% for mucosal carcinoma, with no significant difference between groups. The functional results were satisfactory for 99% of patients, and the cosmetic results were satisfactory for 92%. Maximal toxicity observed was Grade 2. Conclusions: Low-dose-rate brachytherapy can be used to treat lip carcinomas at Stages T1 and T2 as the only treatment with excellent results for local control and relapse-free survival. The benefits of brachytherapy are also cosmetic and functional, with 91% of patients having no side effects.

    Summary Background Long-term hormone therapy has been the standard of care for advanced prostate cancer since the 1940s. STAMPEDE is a randomised controlled trial using a multiarm, multistage platform design. It recruits men with high-risk, locally advanced, metastatic or recurrent prostate cancer who are starting first-line long-term hormone therapy. We report primary survival results for three research comparisons testing the addition of zoledronic acid, docetaxel, or their combination to standard of care versus standard of care alone. Methods Standard of care was hormone therapy for at least 2 years; radiotherapy was encouraged for men with N0M0 disease to November, 2011, then mandated; radiotherapy was optional for men with node-positive non-metastatic (N+M0) disease. Stratified randomisation (via minimisation) allocated men 2:1:1:1 to standard of care only (SOC-only; control), standard of care plus zoledronic acid (SOC + ZA), standard of care plus docetaxel (SOC + Doc), or standard of care with both zoledronic acid and docetaxel (SOC + ZA + Doc). Zoledronic acid (4 mg) was given for six 3-weekly cycles, then 4-weekly until 2 years, and docetaxel (75 mg/m2) for six 3-weekly cycles with prednisolone 10 mg daily. There was no blinding to treatment allocation. The primary outcome measure was overall survival. Pairwise comparisons of research versus control had 90% power at 2·5% one-sided α for hazard ratio (HR) 0·75, requiring roughly 400 control arm deaths. Statistical analyses were undertaken with standard log-rank-type methods for time-to-event data, with hazard ratios (HRs) and 95% CIs derived from adjusted Cox models. This trial is registered at ClinicalTrials.gov (NCT00268476) and ControlledTrials.com (ISRCTN78818544). Findings 2962 men were randomly assigned to four groups between Oct 5, 2005, and March 31, 2013. Median age was 65 years (IQR 60–71). 1817 (61%) men had M+ disease, 448 (15%) had N+/X M0, and 697 (24%) had N0M0. 165 (6

    damage that would result from acid etching, base damage (as a result of a sludge spill or splatter), gamma radiation damage, and/or accidental scratching (due to manipulator/tool contact). Although identified as a potential solution, the Phase 1 testing was relatively short-term with exposure times up to 1-2 months for the acid and gamma radiation tests. Phase 2 testing included longer exposure times for the acid resistance (up to 456 days) and gamma radiation exposure (700 days with a cumulative gamma dose of {approx}3.1 x 10{sup 5} rad) assessments. The tear-off system continued to perform well in these longer-term acid resistance testing and gamma exposure conditions. Complete removal of the tear-offs after these long-term exposure times indicate that not only could visual clarity be restored but the mechanical integrity could be retained. The results also provided insight into the ability of the ProTec tear-off system to withstand the chemical and physical abuses expected in off-normal shielded cells operations. The conceptual erasing of scratches or marks by excessive manipulator abuse was demonstrated in the SRNL Shielded Cells mock-up facility through the removal of the outer layer tear-off with manipulators. In addition, the Phase 2 testing included an in-situ assessment of a prototype tear-off system in the DWPF Sampling Cells where the system was exposed to actual field conditions including radioactive sources, acidic and basic environments, dusting, and chemical cleaning solutions over a 5-6 month period. DWPF personnel were extremely satisfied with the performance (including the successful removal of 3 layers with manipulators) of the ProTec tear-off system under actual field conditions. The successful removal of the outer layer tear-offs with the manipulator, using tabs not specifically designed for remote operations, demonstrates that the system is 'manipulator-friendly' and could be implemented in a remote environment.

    Thirty-one children under the age of 15 years with verified medulloblastoma were treated at Addenbrookes Hospital from 1940 to 1976. In addition to surgical treatment, all received high dose irradiation to the whole neuraxis. Nine were still alive in 1979, of whom eight were examined. All these patients showed some residual problems, but five were leading active lives and had only minor physical disability. There was evidence of disturbance in growth, with shortening of the spine in relation to the limbs, in all the children. The height centile was lower than expected from parental height in four and one was severely dwarfed. Growth hormone secretion in response to exercise was, however, normal in five of six patients tested. Three children also showed failure of growth of the jaw sufficiently severe to be a cosmetic problem. Frank mental retardation was present in three children. A raised resting TSH level was found in two children, one of whom had a multinodular goiter. Of the three children with severe problems, two had been treated when under two years of age. Long-term follow-up of children who survive medulloblastoma is clearly necessary and consideration should perhaps be given to revision of current treatment regimes in very young children.

    Based on solid scientific evidence, new generation drug-eluting stents (DES) have become established as the standard of care in interventional cardiology. With at least similar safety and superior efficacy over uncoated bare metal stents (BMS) in various scenarios and including patients with increased bleeding risk, there are probably no remaining indications favoring the use of BMS. Additional developments regarding the platform, drug elution characteristics and polymer design were aimed at optimizing DES with even better outcomes. Although there is no lack of new variations, none has proven to be superior and several non-inferiority trials lacked statistical power, which precludes the label third generation (over second generation or new generation DES). While it is recognized that potential long-term advantages of bioresorbable scaffolds cannot be expected at this stage from the current ABSORB III trial, the safety and efficacy are encouraging. Beyond procedural aspects, such as intracoronary imaging, variations in duration of antiplatelet therapy should help to improve outcomes but still require careful individual weighting of ischemic vs. bleeding risk.

    Tennis elbow (TE) is one of the commonest myotendinosis. Different treatment options are available and autologous blood injection has emerged as the one of the acceptable modalities of treatment. Long term studies over a larger group of patients are however lacking. The purpose of this study was to evaluate these patients on longer durations. One-hundred and twenty patients of TE, who failed to respond to conventional treatment including local steroid injections were taken up for this prospective study over the period from year 2005 to 2011 and were followed up for the minimum of 3 years (range 3-9 years). Two mL of autologous blood was taken from the ipsilateral limb and injected into the lateral epicondyle. The effectiveness of the procedure was assessed by Pain Rating Sscale and Nirschl Staging, which was monitored before the procedure, at first week, monthly for first three months, at 6 months and then 3 monthly for first year, six monthly for next 2 years and then yearly. Statistical analysis was done and a P value of <0.05 was taken as significant. The patients (76 females and 44 males) were evaluated after procedure. The mean age group was 40.67±8.21. The mean follow up was 5.7±1.72 (range 3 to 9 years). The mean pain score and Nirschl stage before the procedure was 3.3±0.9 and 6.2±0.82 respectively. At final follow up the pain score and Nirschl were 1.1±0.9 and 1.5±0.91 respectively. Autologous blood injection was found to be one of the modalities for treatment of TE. Being cheap, available and easy method of treatment, it should be considered as a treatment modality before opting for the surgery. Universal guidelines for the management of tennis elbow should be made as there is lot of controversy regarding the treatment. PMID:25568727

    Purpose: To assess the dose–response relationship for stomach cancer after radiation therapy for cervical cancer. Methods and Materials: We conducted a nested, matched case–control study of 201 cases and 378 controls among 53,547 5-year survivors of cervical cancer diagnosed from 1943 to 1995, from 5 international, population-based cancer registries. We estimated individual radiation doses to the site of the stomach cancer for all cases and to corresponding sites for the matched controls (overall mean stomach tumor dose, 2.56 Gy, range 0.03-46.1 and after parallel opposed pelvic fields, 1.63 Gy, range 0.12-6.3). Results: More than 90% of women received radiation therapy, mostly with external beam therapy in combination with brachytherapy. Stomach cancer risk was nonsignificantly increased (odds ratio 1.27-2.28) for women receiving between 0.5 and 4.9 Gy to the stomach cancer site and significantly increased at doses ≥5 Gy (odds ratio 4.20, 95% confidence interval 1.41-13.4, P{sub trend}=.047) compared with nonirradiated women. A highly significant radiation dose–response relationship was evident when analyses were restricted to the 131 cases (251 controls) whose stomach cancer was located in the middle and lower portions of the stomach (P{sub trend}=.003), whereas there was no indication of increasing risk with increasing dose for 30 cases (57 controls) whose cancer was located in the upper stomach (P{sub trend}=.23). Conclusions: Our findings show for the first time a significant linear dose–response relationship for risk of stomach cancer in long-term survivors of cervical cancer.

    Purpose: To examine the effect of internal mammary node irradiation (IMNI) on disease-free survival (DFS) and overall survival (OS) in breast cancer patients treated with modified radical mastectomy and postoperative radiation therapy. Methods and Materials: Between 1994 and 2002, 396 patients with stage II-III breast cancer were treated with postmastectomy radiation therapy with (n=197) or without (n=199) IMNI. Patients who received neoadjuvant chemotherapy were excluded. IMNI was administered at the clinical discretion of the treating physician. Median RT dose was 50.4 Gy (range, 45.0-59.4 Gy) in 28 fractions, with inclusion of the supraclavicular fossa in 96% of patients. Adjuvant chemotherapy was administered to 99.7% of the patients and endocrine therapy to 53%. Results: The median follow-up was 149 months (range, 124-202). IMNI patients had more advanced nodal stage and non-high grade tumors than those without IMNI (P<.001). Otherwise, disease and treatment characteristics were well balanced. The 10-year DFS with and without IMNI was 65% and 57%, respectively (P=.05). Multivariate analysis demonstrated that IMNI was an independent, positive predictor of DFS (hazard ratio [HR], 0.70; P=.02). Benefits of IMNI in DFS were seen most apparently in N2 patients (HR, 0.44; 95% confidence interval [CI], 0.26-0.74) and inner/central tumors (HR, 0.55; 95% CI, 0.34-0.90). The 10-year OS with and without IMNI was 72% and 66%, respectively (P=.62). The 10-year DFS and OS were 61%, and 69%, respectively. Conclusions: Internal mammary node irradiation significantly improved DFS in postmastectomy breast cancer patients. Pending long-term results from randomized trials, treatment of internal mammary nodes should be considered in postmastectomy radiation therapy.

    Purpose Surgery, radiotherapy and chemotherapy are the mainstays of cervical cancer treatment. Many patients receive multiple treatment modalities, each with its own long-term effects. Given the high 5 year survival rate for cervical cancer patients, evaluation and improvement of long-term quality of life are essential. Methods Pertinent articles were identified through searches of PubMed for literature published from 1993-2014. We summarize quality of life data from long-term follow up studies of cervical cancer patients. We additionally summarize small group interviews of Hispanic and non-Hispanic cervical cancer survivors regarding social support and coping. Findings Data is varied in terms of the long term impact of treatment on quality of life but consistent in suggesting that patients who receive radiotherapy as part of their treatment have the highest risk of increased long term dysfunction of bladder and bowel, as well as sexual dysfunction and psychosocial consequences. Rigorous investigations regarding long-term consequences of treatment modalities are lacking. Implications Continued work to improve treatment outcomes and survival should also include a focus on reducing adverse long-term side effects. Providing supportive care during treatment, and evaluating the effects of supportive care, may reduce the prevalence and magnitude of long-term sequelae of cervical cancer, which will in turn improve quality of life and quality of care.

    Objective: We compared long-term clinical outcomes of upper urinary tract transitional cell carcinoma (TCC) patients treated by retroperitoneoscopic nephroureterectomy (RNU) or open radical nephroureterectomy (ONU). Methods: Upper urinary tract TCC patients were treated with RNU (n = 86) or ONU (n = 72) and followed-up for more than three years. Demographic and clinical data, including preoperative indexes, intraoperative indexes and long-term clinical outcomes, were retrospectively compared to determine long-term efficacy of the two procedures. Results: The RNU and ONU groups were statistically similar in age, gender, previous bladder cancer history, tumour location, pathologic tumour stage, pathologic node metastasis or tumour pathologic grade. The original surgery time required for both RNU and ONU was statistically similar, but RNU was associated with a significantly smaller volume of intraoperative estimated blood loss and shorter length of postoperative hospital stay. Follow-up (average: 42.4 months, range: 3–57) revealed that the RNU 3-year recurrence-free survival rate was 62.8% and the 3-year cancer specific survival rate was 80.7%. In the ONU group, the 3-year recurrence-free survival and the three-year cancer-specific survival rates were 59.2% and 80.3%, respectively. Neither of the survival rates were statistically different between the two groups. T stage, grade, lymph node metastasis and bladder tumour history were risk factors for tumour recurrence; the operation mode and the bladder cuff incision mode had no correlation with the recurrence-free survival. Conclusion: The open surgery strategy and the retroperitoneoscopic nephroureterectomy strategy are equally effective for treating upper urinary tract TCC. However, the RNU procedure is less invasive, and requires a shorter duration of postoperative hospitalized care; thus, RNU is recommended as the preferred strategy. PMID:22630340

    Context The death of a child from cancer affects the entire family. Little is known about the long-term psychosocial outcomes of bereaved siblings. Objectives To describe: (1) the prevalence of risky health-behaviors, psychological distress, and social support among bereaved siblings; (2) potentially modifiable factors associated with poor outcomes. Methods Bereaved siblings were eligible for this dual-center, cross-sectional, survey-based study if they were ≥16 years-old and their parents had enrolled in one of three prior studies about caring for children with cancer at end of life. Linear regression models identified associations between personal perspectives before, during, and after the family's cancer experience and outcomes (health-behaviors, psychological distress, and social support). Results Fifty-eight siblings completed surveys (62% response rate). They were approximately 12 years bereaved, with a mean age of 26 years at the time of the survey (SD=7.8). Anxiety, depression, and illicit substance use increased during the year following their brother/sister's death, but then returned to baseline. Siblings who reported dissatisfaction with communication, poor preparation for death, missed opportunities to say “goodbye,” and/or a perceived negative impact of the cancer experience on relationships tended to have higher distress and lower social support scores (p<0.001-0.031). Almost all siblings reported their loss still affected them; half stated the experience impacted current educational and career goals. Conclusion How siblings experience the death of a child with cancer may impact their long-term psychosocial well-being. Sibling-directed communication and concurrent supportive care during the cancer experience and the year following sibling death may mitigate poor long-term outcomes. PMID:24880001

    Objective Increasing age and cancer history are related to impaired physical function. Since physical activity has been shown to ameliorate age-related functional declines, we evaluated the association between physical activity and function in older, long-term colorectal cancer survivors. Methods In 2006–2007, mailed surveys were sent to colorectal cancer survivors, aged ≥65 years when diagnosed during 1995 – 2000, and identified through a state cancer registry. Information on physical activity, physical function and relevant covariates was obtained and matched to registry data. Analysis of covariance and linear regression were used to compare means and trends in physical function across levels of activity in the final analytic sample of 843 cases. Results A direct, dose-dependent association between physical activity and function was observed (ptrend <.001), with higher SF-36 physical function subscores in those reporting high vs. low activity levels (65.0 ± 1.7 vs. 42.7 ± 1.7 (mean ± standard error)). Walking, gardening, housework, and exercise activities were all independently related to better physical function. Moderate-vigorous intensity activity (ptrend <.001) was associated with function, but light activity (ptrend =0.39) was not. Conclusion Results from this cross-sectional study indicate significant associations between physical activity and physical function in older, long-term colorectal cancer survivors. PMID:19123055

    Hyperprolactinemia is a rare endocrine disorder in childhood, which may result from hypophyseal adenoma. We aimed to review the etiologic reasons and clinical features in hyperprolactinemia patients retrospectively. The mean age of 11 female patients at diagnosis was 14.2 ± 1.3 years. Five patients had microadenoma, four patients had macroadenoma, and two patients were diagnosed with idiopathic hyperprolactinemia. The most frequent symptoms were menstrual disorders, headache, and galactorrhea, and one-third of the patients had obesity at diagnosis. There was no anterior pituitary hormone deficiency. All patients received bromocriptine as initial therapy; only two patients with macroadenoma and one patient with microadenoma were switched to cabergoline. Transsphenoidal surgery was performed for a patient with macroadenoma, who had cavernous sinus invasion and visual field defect. Medical treatment should be the first-line treatment option in both microadenoma and macroadenoma cases without any neurological signs. Surgery should be employed with limited indications.

    Animal models of human diseases of the central nervous system, generalized anxiety disorder included, are essential for the study of the brain-behavior interface and obligatory for drug development; yet, these models fail to yield new insights and efficacious drugs. By increasing testing duration hundredfold and arena size tenfold, and comparing the behavior of the common animal model to that of wild mice, we raise concerns that chronic anxiety might have been measured at the wrong time, for the wrong duration, and in the wrong animal. Furthermore, the mice start the experimental session with a short period of transient adaptation to the novel environment (habituation period) and a long period reflecting the respective trait of the mice. Using common measures of anxiety reveals that mice exhibit opposite results during these periods suggesting that chronic anxiety should be measured during the post-habituation period. We recommend tools for measuring the transient period, and provide suggestions for characterizing the post habituation period. PMID:23119008

    The aim of the study was assessment of efficacy of internal urethrotomies made in Research Institute of Urology and city urological hospital N 47. A total of 802 endoscopic operations were performed in 644 male patients aged from 16 to 89 years (mean age 58.6 years) with urethral stricture in 1994-2004. Internal optic urethrotomy was made in 733 cases with a cold knife, in 52--with electric knife and in 17 cases--with laser. Endoscopic urethral resection was conducted in 47 cases. The strictures (0.5-8 cm long, mean 1.4 cm) located most frequently in the bulbous urethra (n=426, 66.1%). Short-term results (12 months) of endoscopic treatment of urethral strictures showed that efficacy of the primary internal urethrotomy conducted according to the authors' technique reached 80.4%. Endoscopic reoperations (from 1 to 6) were performed in 98 (19.6%) patients. A complete rehabilitation (follow-up 9 years maximum) including stenting was achieved in 95.1% patients. In 32 (4.9%) patients endoscopic and rehabilitation measures failed to bring about satisfactory clinical outcomes. These patients were treated with open urethroplasty. Thus, internal optic urethrotomy is an effective therapeutic method. After primary urethrotomy recurrences of the strictures to be reoperated reach 19.6%. These can be successfully managed by endoscopic reoperations and rehabilitation measures. PMID:18254221

    An advanced electronically ballasted lighting control system was installed in a portion of an office building to measure the energy and demand savings. The lighting control system used an integrated lighting control scenario that included daylight following, lumen depreciation correction, and scheduling. The system reduced lighting energy on weekdays by 62% and 51% in the north and south daylit zones, respectively, compared to a reference zone that did not have controls. During the summer, over 75% energy savings were achieved on weekdays in the north daylit zone. Even in the south interior zone, which benefitted lime from daylight, correction strategies and adjustment of the aisleway lights to a low level resulted in energy use of only half that of the reference zone. Although, in general, the savings varied over the year due to changing daylight conditions, the energy reduction achieved with controls could be fit using a simple analytical model. Significant savings also occurred during core operating hours when it is more expensive to supply and use energy. Compared to the usage in the reference zone, energy reductions of 49%, 44%, and 62% were measured in the south daylight, south interior, and north daylight zones, respectively, during core operating hours throughout the year. Lighting energy usage on weekends decreased dramatically in the zones with controls, with the usage in the north daylit zone only 10% that of the reference zone. A simple survey developed to assess occupant response to the lighting control system showed that the occupants were satisfied with the light levels provided.

    Purpose: We have previously shown that delivering targeted radiotherapy to the tumour bed intraoperatively is feasible and desirable. In this study, we report on the feasibility, safety, and long-term efficacy of TARGeted Intraoperative radioTherapy (Targit), using the Intrabeam system. Methods and Materials: A total of 300 cancers in 299 unselected patients underwent breast-conserving surgery and Targit as a boost to the tumor bed. After lumpectomy, a single dose of 20 Gy was delivered intraoperatively. Postoperative external beam whole-breast radiotherapy excluded the usual boost. We also performed a novel individualized case control (ICC) analysis that computed the expected recurrences for the cohort by estimating the risk of recurrence for each patient using their characteristics and follow-up period. Results: The treatment was well tolerated. The median follow up was 60.5 months (range, 10-122 months). Eight patients have had ipsilateral recurrence: 5-year Kaplan Meier estimate for ipsilateral recurrence is 1.73% (SE 0.77), which compares well with that seen in the boosted patients in the European Organization for Research and Treatment of Cancer study (4.3%) and the UK STAndardisation of breast RadioTherapy study (2.8%). In a novel ICC analysis of 242 of the patients, we estimated that there should be 11.4 recurrences; in this group, only 6 recurrences were observed. Conclusions: Lumpectomy and Targit boost combined with external beam radiotherapy results in a low local recurrence rate in a standard risk patient population. Accurate localization and the immediacy of the treatment that has a favorable effect on tumour microenvironment may contribute to this effect. These long-term data establish the long-term safety and efficacy of the Targit technique and generate the hypothesis that Targit boost might be superior to an external beam boost in its efficacy and justifies a randomized trial.

    We compare employment and usual hours of work for prime-age cancer survivors from the Penn State Cancer Survivor Survey to a comparison group drawn from the Panel Study of Income Dynamics using cross-sectional and difference-in-differences regression and matching estimators. Because earlier research has emphasized workers diagnosed at older ages, we focus on employment effects for younger workers. We find that as long as two to six years after diagnosis, cancer survivors have lower employment rates and work fewer hours than other similarly-aged adults. PMID:21429606

    Abstract Background Despite the theoretical advantages of laparoscopic surgery, it is still not considered the standard treatment for colorectal cancer patients because of criticism concerning oncologic stability. This study aimed at examining the short- and long-term follow-up results of laparoscopic surgery versus open surgery for colorectal cancer and at investigating clinical outcomes, oncologic safety, and any potential advantages of laparoscopic colorectal cancer resection. Subjects and Methods We retrospectively analyzed a database containing the information about patients who underwent surgery for stage I–III colorectal cancer from January 2004 to January 2012 at our institution. Results The patients who underwent the laparoscopic-assisted procedure showed a significantly faster recovery than those who underwent open surgery, namely, less time to first passing flatus (P=.041), time of first bowel motion (P=.04), time to resume normal diet (P=.043), and time to walk independently (P=.031). Laparoscopic colorectal surgery caused less pain for patients, leading to lower need of analgesic (P=.002) and less hospital recovery time (P=.034), compared with patients who underwent open surgery. No differences were found in 3- and 5-year overall and disease-free survival rates. Conclusions Our results suggested that the laparoscopic approach was as safe as the open alternative. Laparoscopic-assisted surgery has been shown to be a favorable surgical option with better short-term outcomes and similar long-term oncological control compared with open resection. PMID:23004676

    2007-12-01

    This article examines the concept of survivorship and the adoption of the "survivor identity" by those who have been treated for cancer. First, we review recent and growing theoretical and empirical literatures on cancer and identity and identity transformation. With that review as background, we present our own research findings from 2 separate studies on survivorship and identity. Our data suggest that most older adults who have survived cancer for at least 5 years, identify as cancer survivors and/or as ex-patients rather than as victims or patients. Most also view being a survivor as an important part of who they are, do not see themselves as less whole, and are not overly concerned about how others view them. To the degree that a survivor orientation is associated with better mental health outcomes and encourages health promotion and appropriate symptom monitoring, it can reinforce the effects of the quality medical care provided by clinical staff. The support of clinicians encouraging this orientation, where it is appropriate, may further enhance the quality of life of individuals who living with a history of cancer. PMID:17952742

    Childhood cancer is rare but improvements in treatment over the past five decades have resulted in a cohort of more than 30,000 long-term survivors of childhood cancer in the UK with more added annually. These long-term survivors are at risk of late effects of cancer treatment which replace original tumour recurrence as the leading cause of premature death. Second neoplasms are a particular risk and in the central nervous system meningiomas occur increasingly with increased radiation dose to central nervous system tissue and length of time after exposure, resulting in a 500-fold increase above that expected in the normal population by 40 years of follow up. This multidisciplinary author group and others met to discuss the issue. Our pooled information, and consensus that screening should only follow symptoms, was published online by the Royal College of Radiologists in 2013. We outline here the current knowledge and management of these neoplasms secondary to childhood cancer treatment. PMID:25057388

    Due to cisplatin-based chemotherapy, the survival rate of testicular cancer patients approaches 90%. Chemo- or radiotherapy may cause long-term complications, e.g. cardiovascular disease, secondary cancers and reduced fertility. Sperm cryopreservation is recommended depending on the extent of therapy and should be performed before orchiectomy. Furthermore, patients should be informed about long-term complications and their possible reduction by optimizing the risk factor profile. PMID:19234684

    Purpose: Concomitant treatment with radiation therapy and cisplatin (CDDP) remains the gold standard for bladder preservation in the treatment of muscle-invasive bladder cancer (MIBC). We present the long-term results of a phase 1 clinical trial to assess the association of twice-weekly gemcitabine with CDDP and radiation therapy in this setting. Methods and Materials: Patients with pT2-pT4N0M0 MIBC without hydronephrosis or diffuse carcinoma in situ were enrolled in this study. After maximal transurethral resection of the bladder tumor, patients received concomitant radiation therapy (63 Gy in 1.8 fractions) and chemotherapy (CDDP 20 mg/m²/day over 4 days every 21 days and gemcitabine twice a week). The starting dose of gemcitabine was 15 mg/m² with dose escalation to 20, 25, and 30 mg/m². The primary endpoint was the maximum tolerated dose (MTD). Secondary endpoints included toxicity and tumor control. Results: Fourteen patients were enrolled. Dose-limiting toxicity occurred in 2 patients treated with 30 mg/m² gemcitabine (grade 4 thrombocytopenia and severe impairment of World Health Organization performance status, respectively). Nine patients received the complete chemoradiation therapy protocol. The recommended dose of gemcitabine was 25 mg/m². The median follow-up time was 53 months, and the overall and disease-specific 5-year survival rates were 62% and 77%, respectively. Among the patients who received the complete treatment, bladder-intact survival was 76% at 5 years, and the median overall survival was 69.6 months. Conclusions: This regimen was well tolerated. The gemcitabine MTD was 25 mg/m². Bladder preservation and disease control were promising. A multicenter phase 2 randomized trial is ongoing.

    Background Taking care of children diagnosed with cancer affects parents’ professional life. The impact in the long-term however, is not clear. We aimed to compare the employment situation of parents of long-term childhood cancer survivors with control parents of the general population, and to identify clinical and socio-demographic factors associated with parental employment. Methods As part of the Swiss Childhood Cancer Survivor Study, we sent a questionnaire to parents of survivors aged 5–15 years, who survived ≥5 years after diagnosis. Information on control parents of the general population came from the Swiss Health Survey (restricted to men and women with ≥1 child aged 5–15 years). Employment was categorized as not employed, part-time, and full-time employed. We used generalized ordered logistic regression to determine associations with clinical and socio-demographic factors. Clinical data was available from the Swiss Childhood Cancer Registry. Results We included 394 parent-couples of survivors and 3’341 control parents (1’731 mothers; 1’610 fathers). Mothers of survivors were more often not employed (29% versus 22%; ptrend = 0.007). However, no differences between mothers were found in multivariable analysis. Fathers of survivors were more often employed full-time (93% versus 87%; ptrend = 0.002), which remained significant in multivariable analysis. Among parents of survivors, mothers with tertiary education (OR = 2.40, CI:1.14–5.07) were more likely to be employed. Having a migration background (OR = 3.63, CI: 1.71–7.71) increased the likelihood of being full-time employed in mothers of survivors. Less likely to be employed were mothers of survivors diagnosed with lymphoma (OR = 0.31, CI:0.13–0.73) and >2 children (OR = 0.48, CI:0.30–0.75); and fathers of survivors who had had a relapse (OR = 0.13, CI:0.04–0.36). Conclusion Employment situation of parents of long-term survivors reflected the more traditional parenting roles

    Objective Magnetic resonance imaging (MRI) is useful for staging endometrial cancer. The treatment and prognosis of MRI-invisible endometrial cancer remain unclear. The purpose of this study was to retrospectively evaluate the long-term outcomes of patients with MRI-invisible endometrial cancer. Methods Between February 1995 and December 2011, we reviewed the medical records of 433 patients with endometrial cancer, which was staged IA on MRI. Of these patients, 89 had MRI-invisible cancer and 344 had MRI-visible cancer. Both cancers were treated with simple hysterectomy with or without lymph node dissection according to the surgeon's decision. Both cancers were compared regarding pathologic findings, recurrence rates, and survival rates. Results The median sizes of MRI-invisible and MRI-visible cancers were 4 mm (0 to 40 mm) and 20 mm (0 to 89 mm), respectively (p<0.001). Myometrial invasion of these groups were detected in 20.2% (18/89) and 56.7% (195/344), respectively (p<0.001). Lymphadenectomy and follow-up imaging revealed no lymph node metastasis in patients with MRI-invisible cancers, while those revealed in 4.7% (16/344) of patients with MRI-visible cancers (p=0.052). The recurrence rates of MRI-invisible and MRI-visible cancers were 1.1% (1/89) and 7.8% (27/344), respectively (p=0.026). The recurrence-free survival rates of these groups were 98.9% (88/89) and 91.6% (315/344), respectively (p=0.022). Conclusion MRI-invisible endometrial cancer can be treated with less invasive surgery because of its lower tumor burden and better prognosis. This cancer may not require lymphadenectomy because of no metastasis or recurrence in lymph nodes. PMID:27102247

    A cross-sectional study of 155 participants who underwent genetic testing for Lynch syndrome (LS) examined long-term psychosocial and behavioral outcomes. Participants completed standardized measures of perceived risk, psychosocial functioning, knowledge, and a questionnaire of screening activities. Participants were on average 47.3 years and had undergone testing a mean of 5.5 years prior. Eighty four (54%) tested positive for a LS mutation and 71 (46%) negative. For unaffected carriers, perceived lifetime risk of colorectal cancer was 68%, and surprisingly, 40% among those testing negative. Most individuals demonstrated normative levels of psychosocial functioning. However, 25% of those testing negative had moderate depressive symptoms, as measured by the Center for Epidemiologic Studies for Depression Scale, and 31% elevated state anxiety on the State-Trait Anxiety Inventory. Being female and a stronger escape - avoidant coping style were predictive of depressive symptoms. For state anxiety, similar patterns were observed. Quality of life and social support were significantly associated with lower anxiety. Carriers maintained higher knowledge compared to those testing negative, and were more engaged in screening. In summary, most individuals adapt to genetic test results over the long term and continue to engage in screening. A subgroup, including some non-carriers, may require added psychosocial support.

    A cross-sectional study of 155 participants who underwent genetic testing for Lynch Syndrome (LS) examined long-term psychosocial and behavioral outcomes. Participants completed standardized measures of perceived risk, psychosocial functioning, knowledge, and a questionnaire of screening activities. Participants were on average 47.3 years and had undergone testing a mean of 5.5 years prior. Eighty four (54%) tested positive for a LS mutation and 71 (46%) negative. For unaffected carriers, perceived lifetime risk of colorectal cancer was 68%, and surprisingly, 40% among those testing negative. Most individuals demonstrated normative levels of psychosocial functioning. However, 25% of those testing negative had moderate depressive symptoms, as measured by the Center for Epidemiologic Studies for Depression Scale, and 31% elevated state anxiety on the State-Trait Anxiety Inventory. Being female and a stronger escape – avoidant coping style were predictive of depressive symptoms. For state anxiety, similar patterns were observed. Quality of life and social support were significantly associated with lower anxiety. Carriers maintained higher knowledge compared to those testing negative, and were more engaged in screening. In summary, most individuals adapt to genetic test results over the long term and continue to engage in screening. A subgroup, including some non-carriers, may require added psychosocial support.

    Purpose: To evaluate the long-term efficacy of concurrent radiotherapy with mitomycin-C (MMC)-based or cisplatin (CP)-based combinations in a cohort of patients with locally advanced anal canal carcinoma. Methods and Materials: Between 1988 and 2000, 179 patients with locally advanced anal canal carcinoma were treated at the Instituto Nacional de Cancer with two cycles of chemotherapy during Weeks 1 and 5 of radiotherapy. 5-Fluorouracil (750 mg/m{sup 2} 120-hour infusion or 1,000 mg/m{sup 2} 96-hour infusion) plus CP (100 mg/m{sup 2}) on the first day of each cycle or MMC (10-15 mg/m{sup 2}) on the first day of Cycle 1 was administered concurrent with radiotherapy (total dose, 55-59.4 Gy). Of the 179 patients, 60% were included from a randomized trial initiated at the Instituto Nacional de Cancer in 1991 that compared concurrent chemoradiotherapy with MMC vs. CP. Results: The median follow-up for the whole chemoradiotherapy group was 83 months. The median patient age was 58 years, 57% had Stage T3-T4 tumors, and 35% had N-positive disease. The 5-year cumulative colostomy rate was not significantly different between the CP group (22%) and MMC group (29%; p = .28). The actuarial 10-year overall survival and disease-free survival rate for the CP group was 54% and 49% and for the MMC group was 52% and 53%, respectively (p = .32 and p = .92, respectively). On multivariate analysis, male gender (p = .042) and advanced Stage T3-T4 disease (p <.0001) were statistically significant for worse disease-free survival. Stage T3-T4 (p = .039) and N+ (p = .039) disease remained independently significant for overall survival. Conclusion: Long-term follow-up has confirmed the good results of chemoradiotherapy with CP plus 5-fluorouracil, which seem to provide results equivalent to those with MMC plus 5-fluorouracil.

    Background The aim of this study was to evaluate the long term effects after discharge of a hospital-based geriatric liaison intervention to prevent postoperative delirium in frail elderly cancer patients treated with an elective surgical procedure for a solid tumour. In addition, the effect of a postoperative delirium on long term outcomes was examined. Methods A three month follow-up was performed in participants of the Liaison Intervention in Frail Elderly study, a multicentre, prospective, randomized, controlled trial. Patients were randomized to standard treatment or a geriatric liaison intervention. The intervention consisted of a preoperative geriatric consultation, an individual treatment plan targeted at risk factors for delirium and daily visits by a geriatric nurse during the hospital stay. The long term outcomes included: mortality, rehospitalisation, Activities of Daily Living (ADL) functioning, return to the independent pre-operative living situation, use of supportive care, cognitive functioning and health related quality of life. Results Data of 260 patients (intervention n = 127, Control n = 133) were analysed. There were no differences between the intervention group and usual-care group for any of the outcomes three months after discharge. The presence of postoperative delirium was associated with: an increased risk of decline in ADL functioning (OR: 2.65, 95% CI: 1.02–6.88), an increased use of supportive assistance (OR: 2.45, 95% CI: 1.02–5.87) and a decreased chance to return to the independent preoperative living situation (OR: 0.18, 95% CI: 0.07–0.49). Conclusions A hospital-based geriatric liaison intervention for the prevention of postoperative delirium in frail elderly cancer patients undergoing elective surgery for a solid tumour did not improve outcomes 3 months after discharge from hospital. The negative effect of a postoperative delirium on late outcome was confirmed. Trial Registration Nederlands Trial Register, Trial ID NTR 823

  15. Breast Cancer Survivorship: A Comprehensive Review of Long-Term Medical Issues and Lifestyle Recommendations

    2015-01-01

    Long-term survival rates after a diagnosis of breast cancer are steadily rising. This is good news, but clinicians must also recognize that this brings new challenges to the medical community. As breast cancer becomes a chronic condition rather than a life-threatening illness owing to advances in early diagnosis and more effective treatments, health care practitioners must recognize and manage the long-term sequelae of the constellation of therapeutic modalities. Survivors of breast cancer represent a unique and extremely complex group of patients; not only do they have the challenge of dealing with multiple long-term side effects of treatment protocols, but many are also forced to address the preexisting comorbidities of their therapies, which often include multiple other issues. Therapies have additional and/or additive side effects that may interfere with treatments directed toward the new primary diagnosis of breast cancer. Our mandate is to establish a smooth transition from patient with breast cancer to survivor of breast cancer while providing ongoing and future guidance. Certainly, the information and resources to accomplish this transition are readily available; however, they are scattered throughout the literature and therefore are not easily accessible or available to the primary care physician. It is imperative that the information available regarding survivorship issues be accessible in an organized and useful format. This article is a modest attempt to provide a comprehensive review of the long-term medical issues relevant to survivorship after the diagnosis and treatment of breast cancer. A predicted shortage of oncologists by 2020 is well-recognized. Therefore, the bulk of long-term care will become dependent on the primary care physician. This shift of care means that these physicians will need to be well educated in the long-term medical issues related to breast cancer treatment. PMID:25902343

    Increased survival of patients with childhood cancer has resulted in a growing population of survivors. In France approximately 50,000 alive people have been treated before 20 years old and, as survivors, are at risk for health problems due to disease or cancer therapy (surgery, chemotherapy, radiotherapy). Complications such as cardiovascular or cerebrovascular disease (after radiotherapy or chemotherapy), neurocognitive deficiency, endocrine disorders (hypopituitary axis, or thyroid dysfunction), gonadal function, and second malignancy can be life-threatening and seriously affect quality of life. Upon discharge former patients should be given 'passport', containing a summary of their medical history, treatment (surgery, chemotherapy cumulative doses, characteristics of radiotherapy and organs involved), methods used to preserve fertility, and complications during treatment. Treatments can then be linked to individualized recommendations for follow-up care. The risk of developing long-term complications increases with time and can be aggravated by age-related comorbidity and environmental factors (tobacco, alcohol, obesity). Many regions and treatment centres in France have in place organised long-term follow-up procedures. PMID:26044987

    Purpose: To attempt to improve results of chemoradiation for head and neck cancer. Methods and Materials: From March 1996 to April 2007, 98 patients with head and neck cancer (15 Stage III and 83 Stage IV) were treated with a twice-daily hyperfractionated schedule. Eleven patients presented with N0, 11 with N1, 13 with N2A, 17 with N2B, 24 with N2C, and 22 with N3. Each fraction of treatment consisted of 5 mg/m{sup 2} of carboplatin plus 115 cGy with carbogen breathing. Treatment was given 5 days per week up to total doses of 350 mg/m{sup 2} of carboplatin plus 8050 cGy in 7 weeks. Anemia was corrected with erythropoietin. Results: Ninety-six patients tolerated the treatment as scheduled. All patients tolerated the planned radiation dose. Local toxicity remained at the level expected with irradiation alone. Chemotherapy toxicity was moderate. Ninety-seven complete responses were achieved. After 11 years of follow-up (median, 81 months), actuarial locoregional control, cause-specific survival, overall survival, and nodal control rates at 5 and 10 years were, respectively, 83% and 83%, 68% and 68%, 57% and 55%, and 100% and 100%. Median follow-up of disease-free survivors was 80 months. No significant differences in survival were observed between the different subsites or between the pretreatment node status groups (N0 vs. N+, N0 vs. N1, N0 vs. N2A, N0 vs. N2B, N0 vs. N2C, and N0 vs. N3). Conclusions: Improving results of chemoradiation for advanced head and neck cancer up to the level obtained with current treatments for early-stage tumors is a potentially reachable goal.

    Background: LIM and SH3 protein 1 (LASP-1) is a nucleo-cytoplasmatic signalling protein involved in cell proliferation and migration and is upregulated in breast cancer in vitro studies have shown that LASP-1 might be regulated by prostate-derived ETS factor (PDEF), p53 and/or LASP1 gene amplification. This current study analysed the prognostic significance of LASP-1 on overall survival (OS) in 177 breast cancer patients and addressed the suggested mechanisms of LASP-1-regulation. Methods: Nucleo-cytoplasmatic LASP-1-positivity of breast carcinoma samples was correlated with long-term survival, clinicopathological parameters, Ki67-positivity and PDEF expression. Rate of LASP1 amplification was determined in micro-dissected primary breast cancer cells using quantitative RT–PCR. Cell-phase dependency of nuclear LASP-1-localisation was studied in synchronised cells. In addition, LASP-1, PDEF and p53 expression was compared in cell lines of different tumour entities to define principles for LASP-1-regulation. Results: We showed that LASP-1 overexpression is not due to LASP1 gene amplification. Moreover, no correlation between p53-mutations or PDEF-expression and LASP-1-status was observed. However, nuclear LASP-1-localisation in breast carcinomas is increased during proliferation with peak in G2/M-phase and correlated significantly with Ki67-positivity and poor OS. Conclusion: Our results provide evidence that nuclear LASP-1-positivity may serve as a negative prognostic indicator for long-term survival of breast cancer patients. PMID:20461080

    Bisphosphonates are widely used in the treatment of breast cancer with bone metastases. We report a case of a female with breast cancer presented with a rash around a previous mastectomy site and a discharge lesion on her right chest wall in August 2010. Biopsy of the lesion showed dystrophic calcification and metaplastic bone formation. The patient's history revealed a long term use of zoledronic acid for the treatment of breast cancer with bone metastasis. We stopped the treatment since we believed that the cutaneous dystrophic calcification could be associated with her long term bisphosphonate therapy. Adverse cutaneous events with bisphosphonates are very rare, and dystrophic calcification has not been reported previously. The dystrophic calcification and metaplastic bone formation in this patient are thought to be due to long term bisphosphonate usage. PMID:23956898

    Purpose A few studies have prospectively evaluated changes in quality of life (QoL) after surgery in short-term survivors; however, no prospective study has evaluated the longitudinal changes in QoL in long-terms survivors. We prospectively evaluated the chronological changes in QoL after a gastrectomy over a 5-year postoperative period in a large group of patients. Materials and Methods QoL data from the European Organization for Research and Treatment of Cancer QLQ-C30 and the QLQ-STO22 questionnaires were obtained from 254 patients who completed the entire series of QoL assessments preoperatively and at 1, 2, 3, 4, and 5 years after surgery. Results There was no statistically significant change in global health status/QoL during the 5-year postoperative period. Decreases in QoL from upper gastrointestinal symptoms including diarrhea (p < 0.001), dysphagia (p < 0.001), reflux symptoms (p=0.029), and eating restrictions (p < 0.001) were observed among the long-term survivors. Decreased physical functioning (p < 0.001), role functioning (p < 0.001), and cognitive functioning (p < 0.001), along with fatigue (p=0.045) and a poor body image (p=0.003), negatively impacted the patients’ QoL for a long time. Conclusion Management of gastrointestinal symptoms should be specifically targeted as a part of long-term patient care after a gastrectomy. Proper nutritional care will improve food intake resulting in weight gain and improved physical functioning, role functioning, and body image. In addition, patients should be encouraged to preserve self-esteem and maintain social activity. PMID:27004956

    Successful results of palatal implants in the treatment of obstructive sleep apnea (OSA) have been reported in the short term; however, there are limited data in the long-term results. The aim of this study was to evaluate the long-term results and to determine factors that predicted the responders in patients undergoing palatal implants in the treatment of OSA. A study was undertaken on 92 OSA patients. Palatal implants were conducted to stiffen the soft palate and data were analyzed. Patients tolerated the procedure well. They were examined between 26 and 32 months after the operation (mean 28.9 ± 4.8). Age range was 25-65 years (38.4 ± 10.5) and BMI was 27.3 ± 2.4 kg/m. The mean preoperative ESS score was 12.3 ± 2.6 and long-term ESS was 7.9 ± 1.8 (p < 0.001). The mean VAS for snoring in the baseline was 8.2 ± 1.2 and long-term VAS was 3.8 ± 2.3 (p < 0.001). The mean preoperative LSAT and long-term LSAT were 87.4 ± 6.7 and 89.2 ± 4.8%, respectively (p < 0.01). The mean AHI decreased from 21.7 ± 6.8 to 10.8 ± 4.8 (p < 0.001). Forty-eight (52.2%) patients had long-term surgical response. Responders had significantly lower preoperative BMI, AHI, and MMP level than non-responders. Implant extrusion occurred in seven patients (7.6%) and palatal abscess in one patient (1.1%). Bleeding and airway obstruction were not encountered. Palatal implants in carefully selected patients suffering from mild OSA, give fairly good long-term results and have a low complication rate. PMID:21298386

    Background Whether regional anesthesia is associated with tumor-free and long-term survival is controversial. Here, we focused on whether epidural anesthesia affects the long-term survival of gastric cancer patients after surgery. Material/Methods We obtained the records of 273 patients undergoing gastric cancer surgery between August 2006 and December 2010. All patients received elective surgery, and the end-point was death. The general anesthesia group comprised 116 patients and the epidural-supplemented group comprised 157 patients. The results were analyzed using a multivariable model to determine the relationship between epidural use and long-term survival. Results No obvious association was detected between epidural use and long-term survival according to the Cox model (P=0.522); the adjusted estimated hazard ratio was 0.919 (95% CI 0.71–1.19). However, according to Kaplan-Meier analysis, epidural anesthesia was associated with long-term survival among younger patients (age up to 64) (p=0.042, log-rank) (but not among older patients (p=0.203, log-rank). A lower American Society of Anesthesiologists (ASA) class and less chemoradiotherapy exposure were also associated with a longer survival. However, advanced tumor stage still has a significant negative impact on survival. Conclusions No obvious difference was detected between the 2 anesthesia groups, but younger patients may benefit from epidural anesthesia. PMID:27386842

    Little is known about the relationship between motivational readiness for physical activity and quality of life (QOL) in long-term lung cancer survivors. Long-term survivors are considered those who are living 5 years or more following a cancer diagnosis. This project examined the relationship between a self-report measure of motivational readiness for physical activity and QOL in a sample of 272 long-term lung cancer survivors. Participants (54% male, average age 70 years old) completed the mailed survey an average of 6 years after being diagnosed with lung cancer. Survey measures included the stage of change for physical activity and a set of single item QOL and symptom scales. Thirty-seven percent of respondents reported they currently engaged in regular physical activity (a total of 30 min or more per day, at least 5 days per week). Kruskal-Wallis tests revealed that those who reported engaging in regular physical activity reported a better overall QOL, better QOL on all five domains of QOL functioning (mental, physical, social, emotional, and spiritual), and fewer symptoms compared to those with a sedentary lifestyle. Physical activity level may have important QOL and symptom management benefits for long-term lung cancer survivors. PMID:18243406

    Importance The U.S. Preventive Services Task Force recently recommended the use of aspirin to prevent colorectal cancer and cardiovascular disease among many U.S adults. However, the association of aspirin on risk of other cancer types, and aspirin’s potential population-wide impact on cancer, particularly within the context of screening, remain uncertain. Objective To examine potential benefits of aspirin use for overall and subtype-specific cancer prevention, at a range of doses and duration of use, and estimate the absolute benefit of aspirin in the context of screening. Design Two large prospective cohort studies: the Nurses’ Health Study (NHS, 1980–2010) and Health Professionals Follow-up Study (HPFS, 1986–2012). Setting Health professionals in the United States Participants 88,084 women and 47,881 men participating in the NHS and HPFS who reported aspirin use biennially. Main Outcome Measures Relative risks (RRs) for incident cancers and population attributable risk (PAR). Results During up to 32 years of follow-up, we documented 20,414 cancers among women and 7,571 among men. Compared with nonregular use, regular aspirin use was associated with lower risk of overall cancer (RR 0.97; 95% CI 0.94, 0.99), which was primarily due to a lower incidence of gastrointestinal cancers (RR 0.85; 95% CI 0.80, 0.91), especially colorectal cancers (RR 0.81; 95% CI 0.75, 0.88). The benefit of aspirin on gastrointestinal cancers appeared evident with use of at least 0.5 to 1.5 standard aspirin tablets per week; the minimum duration of regular use associated with lower risk was 6 years. Among individuals aged over 50, regular aspirin use could prevent 33 colorectal cancers (PAR 17.0%) among those who have not undergone a lower endoscopy and 18 colorectal cancers per 100,000 person-years (PAR 8.5%) among those who have. Regular aspirin use was not associated with risk of breast, advanced prostate, or lung cancer. Conclusions and Relevance Long-term aspirin use was

    Purpose Weight gain often occurs after breast cancer diagnosis and significantly impacts the general health of cancer survivors. While the number of breast cancer survivors is increasing, few studies have reported data on weight change beyond 5 years post-diagnosis. We investigated weight change and associated factors in long-term survivors of breast cancer. Patients and Methods Medical records were reviewed on 1363 breast cancer patients and a total of 822 women who had survived beyond 5 years since diagnosis were included in the final analysis. The association between demographic, anthropometric, lifestyle, cancer related factors (including time since diagnosis, treatment modality, pathologic stage, and hormone receptor status), and weight-change over 5 years were examined. Results During an average 8.2 years of follow-up time, mean weight gain was 0.32kg (p = 0.017). 175 (21.3%) patients had gained more than 5% of their weight at diagnosis and their average gain was 5.55kg. Body mass index (BMI) at diagnosis, age at diagnosis, aromatase inhibitor (AI) use, heavy drinking, and type of surgery were associated with relative weight gain (≥5%) in univariate analysis (all p-values<0.05). Patients who were non-obese at diagnosis showed weight gain, while those who were obese at diagnosis lost weight (0.78kg,−1.11kg, respectively, p<0.001). In multivariate analysis, the non-obese group showed odds ratio of 2.7 (p = 0.001) relative to the obese group. Younger age group (age 18–54 years) showed odds ratio of 1.9 (p = 0.021) relative to the older age group (age 55–75 years), and patients who did not use AI showed odds ratio of 2.2 (p = 0.006) relative to women who did. Conclusion Long-term breast cancer survivors who were non-obese at diagnosis are more likely to gain weight than obese survivors. Younger survivors and survivors who have never used AI are also likely to gain weight. PMID:27391162

    Background Endovenous laser ablation (EVLA) is widely performed since the early 2000s, but there are few long-term results. Objectives The aim of this study was to evaluate the long-term results of EVLA employed for treating varicose veins of the lower limbs by duplex ultrasonographic study. Methods A total of 24 limbs of 17 patients who underwent EVLA between 2004 and 2007 were examined with duplex ultrasonographic scans. The mean follow-up period was 66.1 months. Results There were five recurrences of saphenofemoral junction reflux. The occlusion rate was 79.2% at a mean follow-up of 66.1 months. There were 14 recanalizations and 5 recurrences of the great saphenous vein. Five partial and nine total recanalizations were observed. Conclusions EVLA is an effective and minimally invasive treatment for varicose veins. Our long-term result was acceptable, but the result was not outstanding. PMID:27231428

    Background Long-term oxygen therapy (LTOT) is sometimes prescribed for patients with advanced lung cancer who are potential candidates for chemotherapy. The aim of this study was to assess the usefulness of chemotherapy for patients with this disease who require LTOT. Methods The medical records of 40 patients with advanced lung cancer who received LTOT while undergoing systemic chemotherapy at our institution between January 2009 and December 2014 were retrospectively reviewed. Chemotherapy consisted of cytotoxic or molecular-targeted agents. Results Twenty-four patients had adenocarcinoma, 6 had squamous cell carcinoma, and 10 had small cell lung cancer (SCLC). The median survival time from the date of the first chemotherapy cycle performed in conjunction with LTOT was 194 days. In a multivariate analysis, the only factor significantly associated with better prognosis was the line (first or second) of the first chemotherapy with LTOT (hazard ratio =0.42; 95% confidence interval, 0.18 to 0.94). Among the 40 patients, 10 (25%) received chemotherapy during the last 30 days of their lives, 2 of whom died of chemotherapy-related adverse events. Conclusions Chemotherapy for patients with advanced lung cancer who receive LTOT may be acceptable if it is the first- or second-line treatment. However, we should be mindful of the potential overuse of chemotherapy and its negative impact on quality of life. PMID:26904219

    Successful results of genioglossus advancement and hyoid myotomy with suspension (GAHM) in the treatment of obstructive sleep apnoea (OSA) have been reported. However, there have been few studies of long-term results. Forty-six patients with hypopharyngeal obstruction underwent GAHM. Patients had a mean age of 40.1 +/- 4.2 years and a mean body mass index (BMI) of 28.9 +/- 2.1 kg/m(2). The mean follow-up was 39.4 +/- 5.7 months with a range of 37 to 46 months. The mean pre-operative RDI, short-term RDI, and long-term RDI were 47.9 +/- 8.4, 14.2 +/- 3.9, 18.6 +/- 4.1, respectively. The mean post-operative LSAT, short-term LSAT, and long-term LSAT were 81.2 per cent +/- 2.9 per cent, 88.8 per cent +/- 2.7 per cent and 87.2 per cent +/- 3.1 per cent, respectively. The change in BMI was significantly different in the patients with, and without, recurrence (2.1 +/- 0.3 vs 0.4 +/- 0.2.kg/m(2), <0.05). Thirty (65.2 per cent) patients had long-term clinical success, and six (16.7 per cent) patients with short-term success failed long-term. GAHM appears to be an effective procedure and results in long-term success. However, patients with weight gain are at risk of recurrence. PMID:12818058

    We investigate whether private research investments are distorted away from long-term projects. Our theoretical model highlights two potential sources of this distortion: short-termism and the fixed patent term. Our empirical context is cancer research, where clinical trials – and hence, project durations – are shorter for late-stage cancer treatments relative to early-stage treatments or cancer prevention. Using newly constructed data, we document several sources of evidence that together show private research investments are distorted away from long-term projects. The value of life-years at stake appears large. We analyze three potential policy responses: surrogate (non-mortality) clinicaltrial endpoints, targeted R&D subsidies, and patent design.

    Small cell lung cancer (SCLC) is a neuroendocrine lung cancer characterized by fast growth, early dissemination, and rapid resistance to chemotherapy. We identified a population of long-term tumor-propagating cells (TPCs) in a mouse model of SCLC. This population, marked by high levels of EpCAM and CD24, is also prevalent in human primary SCLC tumors. Murine SCLC TPCs are numerous and highly proliferative but not intrinsically chemoresistant, indicating that not all clinical features of SCLC are linked to TPCs. SCLC TPCs possess a distinct transcriptional profile compared to non-TPCs, including elevated MYC activity. Genetic and pharmacological inhibition of MYC in SCLC cells to non-TPC levels inhibits long-term propagation but not short-term growth. These studies identify a highly tumorigenic population of SCLC cells in mouse models, cell lines, and patient tumors and a means to target them in this most fatal form of lung cancer. PMID:27373157

    Purpose: To obtain insight into the long-term (5- to 10-year) effects of prostate cancer and treatment on bowel, urinary, and sexual function, we performed a population-based study. Prostate-specific function was compared with an age-matched normative population without prostate cancer. Methods and Materials: Through the population-based Eindhoven Cancer Registry, we selected all men diagnosed with prostate cancer between 1994 and 1998 in the southern Netherlands. In total, 964 patients, alive in November 2004, received questionnaire; 780 (81%) responded. Results: Urinary problems were most common after a prostatectomy; bowel problems were most common after radiotherapy. Compared with an age-matched normative population both urinary and bowel functioning and bother were significantly worse among survivors. Urinary incontinence was reported by 23-48% of survivors compared with 4% of the normative population. Bowel leakage occurred in 5-14% of patients compared with 2% of norms. Erection problems occurred in 40-74% of patients compared with 18% of norms. Conclusions: These results form an important contribution to the limited information available on prostate-specific problems in the growing group of long-term prostate cancer survivors. Bowel, urinary, and sexual problems occur more often among long-term survivors compared with a reference group and cannot be explained merely by age. Because these problems persist for many years, urologists should provide patients with adequate information before treatment. After treatment, there should be an appropriate focus on these problems.

    Survival after childhood cancer has improved substantially over recent decades. Although cancer in childhood is rare increasingly effective treatments have led to a growing number of long-term survivors. It is estimated that there are between 300,000 and 500,000 childhood cancer survivors in Europe. Such good survival prospects raise important questions relating to late effects of treatment for cancer. Research has shown that the majority will suffer adverse health outcomes and premature mortality compared with the general population. While chronic health conditions are common among childhood cancer survivors, each specific type of late effect is very rare. Long-term effects must be considered particularly when addressing complex multimodality treatments, and taking into account the interaction between aspects of treatment and genotype. The PanCare Network was set up across Europe in order to effectively answer many of these questions and thereby improve the care and quality of life of survivors. The need for a structured long-term follow-up system after childhood cancer has been recognised for some time and strategies for implementation have been developed, first nationally and then trans-nationally, across Europe. Since its first meeting in Lund in 2008, the goal of the PanCare Network has been to coordinate and implement these strategies to ensure that every European survivor of childhood and adolescent cancer receives optimal long-term care. This paper will outline the structure and work of the PanCare Network, including the results of several European surveys, the start of two EU-funded projects and interactions with relevant stakeholders and related projects.

    Background: The community-based incidence of cancer treatment-related long-term consequences is uncertain. We sought to establish the burden of health outcomes that have been associated with treatment among British long-term cancer survivors. Methods: We identified 26 213 adults from the General Practice Research Database who have survived 5 years or more following breast, colorectal or prostate cancer. Four age-, sex- and general practice-matched non-cancer controls were selected for each survivor. We considered the incidence of treatment-associated health outcomes using Cox proportional hazards models. Results: Breast cancer survivors had an elevated incidence of heart failure (hazards ratio (HR) 1.95, 95% confidence interval (CI) 1.27–3.01), coronary artery disease (HR 1.27, 95% CI 1.11–1.44), hypothyroidism (HR 1.26, 95% CI 1.02–1.56) and osteoporosis (HR 1.26, 95% CI 1.13–1.40). Among colorectal cancer survivors, there was increased incidence of dementia (HR 1.68, 95% CI 1.20–2.35), diabetes (HR 1.39, 95% CI 1.12–1.72) and osteoporosis (HR 1.41, 95% CI 1.15–1.73). Prostate cancer survivors had the highest risk of osteoporosis (HR 2.49, 95% CI 1.93–3.22). Conclusions: The study confirms the occurrence of increased incidence of chronic illnesses in long-term cancer survivors attributable to underlying lifestyle and/or cancer treatments. Although the absolute risk of the majority of late effects in the cancer survivors cohort is low, identifying prior risk of osteoporosis by bone mineral density scanning for prostate survivors should be considered. There is an urgent need to improve primary care recording of cancer treatment. PMID:22048030

    Purpose: To describe the long-term outcomes from a completed, multi-institutional phase 4 registry trial using the Contura multilumen balloon (CMLB) breast brachytherapy catheter to deliver accelerated partial breast irradiation (APBI) in patients with early-stage breast cancer. Methods and Materials: Three hundred forty-two evaluable patients were enrolled by 23 institutions between January 2008 and February 2011. All patients received 34 Gy in 10 fractions, delivered twice daily. Rigorous target coverage and normal tissue dose constraints were observed. Results: The median follow-up time was 36 months (range, 1-54 months). For the entire patient cohort of 342 patients, 10 patients experienced an ipsilateral breast tumor recurrence (IBTR). Eight of these IBTR were classified as true recurrences/marginal miss (TRMM), and 2 were elsewhere failures (EF). Local recurrence-free survival was 97.8% at 3 years. For the entire cohort, 88% of patients had good to excellent overall cosmesis. The overall incidence of infection was 8.5%. Symptomatic seroma was reported in only 4.4% of patients. A separate analysis was performed to determine whether improved outcomes would be observed for patients treated at high-volume centers with extensive brachytherapy experience. Three IBTR were observed in this cohort, only 1 of which was classified as a TRMM. Local recurrence-free survival at high-volume centers was 98.1% at 3 years. Overall cosmetic outcome and toxicity were superior in patients treated at high-volume centers. In these patients, 95% had good to excellent overall cosmesis. Infection was observed in only 2.9% of patients, and symptomatic seroma was reported in only 1.9%. Conclusion: Use of the CMLB for APBI delivery is associated with acceptable long-term local control and toxicity. Local recurrence-free survival was 97.8% at 3 years. Significant (grade 3) toxicity was uncommon, and no grade 4 toxicity was observed. Treatment at high-volume centers was associated

    Purpose Negative Helicobacter pylori status has been identified as a poor prognostic factor for survival in gastric cancer (GC) patients who underwent surgery. The aim of this study was to examine the effect of H. pylori eradication on long-term outcomes after distal gastrectomy for GC. Materials and Methods We analyzed the survival of 169 distal GC patients enrolled in a prospective randomized trial evaluating histologic changes of gastric mucosa after H. pylori eradication in the remnant stomach. The outcomes measured were overall survival (OS) and GC recurrence rates. Results The median follow-up duration was 9.4 years. In the modified intention-to-treat analysis including patients who underwent H. pylori treatment (n=87) or placebo (n=82), 5-year OS rates were 98.9% in the treatment group and 91.5% in the placebo group, and Kaplan-Meier analysis showed no significant difference in OS (p=0.957) between groups. In multivariate analysis, no difference in overall mortality was observed between groups (adjusted hazard ratio [aHR] for H. pylori treatment, 0.75; p=0.495) or H. pylori-eradicated status (aHR for positive H. pylori status, 1.16; p=0.715), while old age, male sex, and advanced stage ≥ IIIa were independent risk factors. Six patients in the treatment group (6.9%) and seven patients in the placebo group (8.5%) had GC recurrences, and GC recurrence rates were not different according to H. pylori treatment (5-year GC recurrence rates, 4.6% in the treatment group vs. 8.5% in the placebo group; p=0.652). Conclusion H. pylori eradication for GC patients who underwent distal gastrectomy did not compromise long-term survival after surgery.

    Purpose: The use of altered fractionation radiotherapy (RT) regimens, as well as concomitant chemotherapy and RT, to intensify therapy for locally advanced head-and-neck cancer can lead to increased rates of long-term dysphagia. Methods and Materials: We identified 122 patients who had undergone definitive RT for locally advanced head-and-neck cancer, after excluding those who had been treated for a second or recurrent head-and-neck primary, had Stage I-II disease, developed locoregional recurrence, had <12 months of follow-up, or had undergone postoperative RT. The patient, tumor, and treatment factors were correlated with a composite of 3 objective endpoints as a surrogate for severe long-term dysphagia: percutaneous endoscopic gastrostomy tube dependence at the last follow-up visit; aspiration on a modified barium swallow study or a clinical diagnosis of aspiration pneumonia; or the presence of a pharyngoesophageal stricture. Results: A composite dysphagia outcome occurred in 38.5% of patients. On univariate analysis, the primary site (p = 0.01), use of concurrent chemotherapy (p = 0.01), RT schedule (p = 0.02), and increasing age (p = 0.04) were significantly associated with development of composite long-term dysphagia. The use of concurrent chemotherapy (p = 0.01), primary site (p = 0.02), and increasing age (p = 0.02) remained significant on multivariate analysis. Conclusion: The addition of concurrent chemotherapy to RT for locally advanced head-and-neck cancer resulted in increased long-term dysphagia. Early intervention using swallowing exercises, avoidance of nothing-by-mouth periods, and the use of intensity-modulated RT to reduce the dose to the uninvolved swallowing structures should be explored further in populations at greater risk of long-term dysphagia.

    The occurrence of a second primary esophageal carcinoma (EC) in long-term cancer survivors may represent a late effect of previous radio-chemotherapeutic treatment. To identify the genetic factors that could increase this risk, we analyzed nine variants within ERCC1, XPD, XRCC1 and XRCC3 DNA repair pathway genes, and GSTP1, TP53 and MDM2 genes in 61 patients who received radio-chemotherapy for a prior lymphoma or breast cancer; 29 of them had a second primary EC. This cohort consists of 22 esophageal squamous cell carcinoma (ESCC) and 7 esophageal adenocarcinoma (EADC) patients. A validation cohort of 154 patients with sporadic EC was also included. The XPD Asp312Asn (rs1799793) was found to be associated with the risk of developing second primary ESCC (P=0.015). The resultant variant was also involved in the onset of sporadic ESCC (P=0.0018). To know in advance who among long-term cancer survivors have an increased risk of EC could lead to a more appropriate follow-up strategy. PMID:26054330

    To assess whether gender influences the results of coronary stenting, 158 consecutive women undergoing coronary stenting were compared with 823 consecutive men. Women had more adverse baseline characteristics, a higher hospital mortality, and were independently associated with procedural failure/complications (relative risk 2.4, 95% confidence interval 1.2 to 4.8); however, the long-term event-free survival and the restenosis rate were not influenced by gender.

Malignancies either solid tumors or haematological cancers have not been reported in such population. We report here a rare case of follicular thyroid carcinoma in LTNP-HIV infection. She never had any opportunistic infections. She did not receive anti-retroviral therapy in the entire course of illness and continued to have good quality of life. Treatment of follicular thyroid cancer was similar to other patients without HIV infection. This could be the first case study from India. PMID:26692617

    Survivors of sepsis often experience long-term cognitive and functional decline. Previous studies utilizing lipopolysaccharide injection and cecal ligation and puncture in rodent models of sepsis have demonstrated changes in depressive-like behavior and learning and memory after sepsis, as well as evidence of myeloid inflammation and cytokine expression in the brain, but the long-term course of neuroinflammation after sepsis remains unclear. Here, we utilize cecal ligation and puncture with greater than 80% survival as a model of sepsis. We found that sepsis survivor mice demonstrate deficits in extinction of conditioned fear, but no acquisition of fear conditioning, nearly two months after sepsis. These cognitive changes occur in the absence of neuronal loss or changes in synaptic density in the hippocampus. Sepsis also resulted in infiltration of monocytes and neutrophils into the CNS at least two weeks after sepsis in a CCR2 independent manner. Cellular inflammation is accompanied by long-term expression of pro-inflammatory cytokine and chemokine genes, including TNFα and CCR2 ligands, in whole brain homogenates. Gene expression analysis of microglia revealed that while microglia do express anti-microbial genes and damage-associated molecular pattern molecules of the S100A family of genes at least 2 weeks after sepsis, they do not express the cytokines observed in whole brain homogenates. Our results indicate that in a naturalistic model of infection, sepsis results in long-term neuroinflammation, and that this sustained inflammation is likely due to interactions among multiple cell types, including resident microglia and peripherally derived myeloid cells.

    Purpose: To clarify the immediate effect and long-term results of bronchial artery embolization (BAE) for hemoptysis due to benign diseases and the factors influencing the outcomes.Methods: One hundred and one patients (aged 34-89 years) received bronchial artery embolization with polyvinyl alcohol particles and gelatin sponge for massive or continuing moderate hemoptysis caused by benign pulmonary diseases and resistant to medical treatment.Results: After BAE, bleeding stopped in 94 patients (94%). The immediate effect was unfavorable in cases where feeder vessels were overlooked or the embolization of the intercostal arteries was insufficient. Long-term cumulative hemoptysis non recurrence rates after the initial embolization were 77.7% for 1 year and 62.5% for 5 years. In bronchitis (n 9) and active tuberculosis (n = 4) groups, an excellent (100%) 5-year cumulative non recurrence rate was obtained. The rate was lower in groups with pneumonia/abscess/pyothorax (n = 8) or with pulmonary aspergillosis (n = 9) (53.3%, 1-year cumulative non recurrence). There were higher incidences of early recurrence among patients with massive hemorrhage or more marked vascularity and systemic artery-pulmonary artery shunt in angiography: however, these trends were not statistically significant. Conclusions: BAE can yield long-term benefit in patients with hemoptysis due to benign diseases. Technical problems in the procedure had an impact on the short-term effect. The degree of hemorrhage or the severity of angiographical findings were not significant factors affecting the outcome. The most significant factor affecting long-term results was whether the inflammation caused by the underlying disease was medically well controlled.

    With recognition of the biomechanical role of the meniscus, such as load distribution and joint stability in the knee joint, there has been a shift in the treatment of meniscal tears from open total meniscectomy to preservation of the meniscal functions as much as possible with symptomatic relief. Recently, technical development of meniscal surgery, with advanced arthroscopic equipment and instruments, enables biological reconstruction of load bearing functions in the meniscus deficient knee through allograft tissue transplantation as well as repair of torn menisci. Meniscal allograft transplantation (MAT) has been considered as one of the few viable treatment options for the young meniscectomized knees based on various animal experiments and clinical studies. Still, there is insufficient evidence for the long-term chondroprotective effect of human MAT. Some long-term follow-up studies showed that the technique resulted in graft degeneration, deformation, and tear, and structural changes in the remodeling process in early MAT cases, disrupting functional restoration of the original meniscus. Nevertheless, advanced outcomes are documented in some recent studies. The purpose of this article is to review the mid- and long-term follow-up results of MAT and to improve understanding of MAT with evaluation methods of meniscal transplants using magnetic resonance imaging or second-look arthroscopy.

    : More than 12% of women will be diagnosed with breast cancer at some point in their lives, and 78% of them can be expected to survive for at least 15 years. More than 2.8 million breast cancer survivors currently reside in the United States. After breast cancer treatment, as many as 90% of survivors report physical problems that can reduce functional ability, produce or exacerbate emotional problems, negatively affect body image, and diminish quality of life. Many survivors will seek care for late and long-term effects of treatment, which will not necessarily be recognized as such by health care providers and appropriately treated. In this article, the authors discuss the underlying causes of late and long-term sequelae of breast cancer treatment and describe effective assessment and management strategies. They focus specifically on the most common and potentially debilitating upper body effects of breast cancer surgery and external radiation therapy: lymphedema, axillary web syndrome, postmastectomy pain syndrome, rotator cuff syndrome, adhesive capsulitis, arthralgias, cervical radiculopathy, and brachial plexopathy.

    Patients with advanced testicular cancer (TC) have a very good long-term prognosis owing to cisplatin-based polychemotherapy. Platinum is believed to be excreted at a rapid rate via urine within weeks after chemotherapy. As a new, highly sensitive method has become available detecting even natural background platinum levels in body fluids, this study was set up to analyze urinary and serum platinum levels in long-term survivors of testicular neoplasm after cisplatin based polychemotherapy and to correlate clinical data with urinary and serum platinum levels. Urinary platinum concentrations were measured in 64 healthy controls (C) and 22 male patients (TC) 150 to 3022 days after the last application of i.v. cisplatin using voltammetry after UV-photolysis. In the latter group (TC), serum platinum levels were measured as well. Clinical data were analysed as to long-term organ toxicity. Mean urinary platinum levels were 2700 times higher in the patient group (TC) than natural background noise (p < 0.0001). There was a decline of urinary and serum platinum levels over time, being significantly above normal even 8 years after cisplatin exposure. The only significant variables related to the urine platinum concentration were a) the interval between the last i.v. cisplatin application and time of study and b) the total dose given. Not significant were the number of chemotherapy cycles, pre-therapy renal disease, patient age, tumour resection before/after chemotherapy, site of pre/post therapy resection, clinical staging, histological subtypes or tumour markers. Post-therapy renal disease or peripheral nerve damage were not significantly associated with urinary platinum levels. Our data indicate that even 8 years after cisplatin based chemotherapy 500 times elevated urinary and serum platinum levels can be measured in testicular cancer patients. No organ toxicity related to long-term platinum excretion could be detected. This may be due to our small sample size. PMID

  6. Surgical and conservative treatment of patients with congenital scoliosis: α search for long-term results

    PubMed Central

    2011-01-01

    Background In view of the limited data available on the conservative treatment of patients with congenital scoliosis (CS), early surgery is suggested in mild cases with formation failures. Patients with segmentation failures will not benefit from conservative treatment. The purpose of this review is to identify the mid- or long-term results of spinal fusion surgery in patients with congenital scoliosis. Methods Retrospective and prospective studies were included, reporting on the outcome of surgery in patients with congenital scoliosis. Studies concerning a small numbers of cases treated conservatively were included too. We analyzed mid-term (5 to 7 years) and long-term results (7 years or more), both as regards the maintenance of the correction of scoliosis and the safety of instrumentation, the early and late complications of surgery and their effect on quality of life. Results A small number of studies of surgically treated patients were found, contained follow-up periods of 4-6 years that in the most cases, skeletal maturity was not yet reached, and few with follow-up of 36-44 years. The results of bracing in children with congenital scoliosis, mainly in cases with failure of formation, were also studied. Discussion Spinal surgery in patients with congenital scoliosis is regarded in short as a safe procedure and should be performed. On the other hand, early and late complications are also described, concerning not only intraoperative and immediate postoperative problems, but also the safety and efficacy of the spinal instrumentation and the possibility of developing neurological disorders and the long-term effect these may have on both lung function and the quality of life of children. Conclusions Few cases indicate the long-term results of surgical techniques, in the natural progression of scoliosis. Similarly, few cases have been reported on the influence of conservative treatment. In conclusion, patients with segmentation failures should be treated

    In the 1970s, high failure rates of cemented acetabular components, especially in young patients, in the middle- and long-term prompted a search for alternatives. The Mecring was one of the most popular first generation uncemented, threaded cups widely used in the 1980s for arthroplasty of the hip. First generation threaded cups commonly had smooth surface treatment and showed unacceptably high failure rates in the mid-term. In a consecutive series of 209 patients, 221 threaded uncemented acetabular cups with smooth surface treatment (Mecring) had been implanted in combination with one type of uncemented stem. Patients were followed up clinically and radiographically. The mean time of follow-up was 17 (range 15–20) years. In 91 (41%) hips the acetabular component had been revised or was awaiting revision: two hips for infection and 84 (38%) for aseptic loosening. Five hips were awaiting revision. The survival rate for all revisions including hips awaiting revision was 49% (95% CI: 41–57%) at 17 years. These results support the view that smooth, threaded acetabular components do not provide satisfactory long-term fixation and should be abandoned. Patients with these components must be closely monitored as the failure rate remains high in the long-term. PMID:19629481

    Objectives To report the long-term outcome of laparoscopic retroperitoneal pyeloplasty (LRP) in adults. Patients and methods Thirty patients underwent LRP for primary pelvi-ureteric junction obstruction (PUJO). Anderson–Hynes dismembered pyeloplasty was used in 28 patients and a Foley Y–V pyeloplasty in two. A JJ stent was inserted antegradely during the procedure. Patients were reviewed at 1 month after LRP for stent removal, and then at 6 and 12 months routinely, using excretory urography. Results The mean patient age was 29.7 years, with a female predominance of 60%. Conversion to open surgery was mandated by dense adhesions secondary to previous pyelonephritis in three patients, and difficulty in suturing in one. The mean (range) operative duration was 228 (190–280) min. There was a crossing vessel in 11 patients and it was not transposed in any. The mean hospital stay after LRP was 4.2 days. The mean (range) follow-up was 60 (29–106) months. Of the 26 patients who had complete laparoscopic procedures, 23 had no evidence of obstruction on long-term postoperative intravenous urography and/or diuretic renography. Conclusion LRP combines the high functional success rate of open pyeloplasty in the long term and the minimally invasive morbidity of laparoscopy. PMID:26558113

    Background This cross-sectional study aimed to evaluate the prevalence of depressive disorders and factors associated in long-term cancer survivors. Methods A total of 702 long-term cancer survivors over 5-years in remission were recruited in a university-affiliated tertiary hospital in Korea. Self-report using the Patient Health Questionnaire-2 and the Fatigue Severity Scale assessed depression and fatigue, respectively. Demographic characteristics, cancer-related clinical characteristics, comorbidity, health behaviors, and physical symptoms were assessed through the review of medical records or a structured self-administered questionnaire. Results We identified 26.1% of patients who had a depressed mood or displayed a loss of interest. The most prevalent primary site of cancer was the stomach (65.2%), followed by lung, breast, colorectal, and thyroid cancer. We also found that 5.7% of subjects experienced double or triple primary cancers. Larger proportion among depressive group (89.1%) complained at least one physical problem than among non-depressive group (53.2%). Physical symptoms including sleep problems, dry mouth, indigestion, pain, decreased appetite, and febrile sense were more frequent in the depressive group than in the non-depressive group. The Fatigue Severity Scale scores were higher in the depressive group than in the non-depressive group (P<0.001). Multiple logistic regression analysis showed that the highest tertile level of fatigue (odds ratio, 7.31; 95% confidence interval, 3.81–14.02) was associated with the increased risk of depression. Conclusion These findings suggest that careful concern about depression is necessary in long-term cancer survivors. Fatigue may be a surrogate sign for depression, and warrants further evaluation.

    We present a possible adverse reaction related to long-term use of Doxil(®) in female patients. We believe that long-term use of Doxil(®) may predispose female patients to oral squamous cell carcinoma. The patients in this report were not exposed to the common risk factors related to oral cancer formation such as smoking or alcohol consumption. Both patients were 59-year-old females. The first patient was diagnosed in 2001 with stage IIIC ovarian cancer. Seven years following treatment with Doxil(®), she was diagnosed with stage III squamous cell carcinoma of the right maxilla. The second patient was diagnosed with Kaposi's sarcoma with evidence of spread to the lungs. Four years following treatment with Doxil(®) she was diagnosed with stage I squamous cell carcinoma of the left maxilla. A literature review did not reveal any report on Doxil(®) and predisposition to oral cancer; however, we found an abstract that was presented at the last annual meeting of the American Society of Clinical Oncology (ASCO) by Cannon et al. When we combine the data from Cannon et al. and the data presented here, a total of six female patients developed an epithelial carcinoma of the oral cavity following long-term treatment with Doxil(®). We believe that a large-scale study should be initiated on patients that were treated with Doxil(®) for more than 3 years, since these patients might be at risk for developing secondary cancer of the oral cavity.

    Patients with pancreatic cancer have a high frequency of concurrent diabetes. This study is aimed to demonstrate the impact of diabetes on clinical outcome of pancreatic cancer. Clinical and epidemiological information was collected from medical records or by personal interview in 1328 patients with pancreatic ductal adenocarcinoma. Diabetes was defined by a known medical history, or abnormal fasting blood glucose (FBG) and HbA1c levels within three months of the cancer diagnosis. Duration of ≤3 years was used as the cutoff to arbitrarily define the new-onset and long-term diabetes. Logistic regression, Kaplan-Meier plot, log-rank test and Cox regression models were employed in the data analysis. Elevated level of FBG or HbA1c was observed in 24.7% and 11.5% of the patients without a known diabetes history, respectively. The prevalence of DM was 44.4% and was comparable by strata of tumor stage. New-onset diabetes was a significant independent predictor for risk of death in metastatic patients (HR=1.35, 95% CI=1.11-1.63, P=0.002) and in all patients (HR=1.23, 95% CI=1.09-1.40, P=0.001). Both new-onset and long term diabetes were significantly associated with older age, obesity, hypertension and coronary artery disease as well as weight loss. New-onset diabetes was also significantly related to larger tumors and elevated level of CA19-9 but not to tumor site and presence of biliary obstruction. Diabetes in general and new-onset diabetes in particular, is associated with poor outcome of pancreatic cancer. New-onset and long-term diabetes share common risk factors for type 2 diabetes.

    The aim of the study is to report the long-term outcome and secondary tumours of early breast cancer patients of adjuvant CNF (cyclophosphamide, mitoxantrone, and 5-fluorouracil) chemotherapy. One hundred and ninety four patients, 185 primary early breast cancer and nine locoregionally recurrent breast cancer patients, were entered onto the trial between May 1986 and November 1993. The therapies included surgery, radiation therapy, adjuvant CNF chemotherapy, and tamoxifen according to hormonal status. Some of patients were treated twice with CMF (methotrexate). The median follow-up time was 12.9 years. Eighty nine (48%) primary breast cancers relapsed, and six locoregional breast cancers relapsed. After 5-10 years the relapse incidence decreased notably. Eighty three patients died of breast cancer, and nine of other causes. Two cases of leukemia, six cases of skin cancer, two cases of Hodgkin's disease, two cases of meningioma, and two cases of endometrial cancer were observed. This article confirms the feasibility of adjuvant CNF for early breast cancer patients. Questions of possible causability of secondary cancer have yet to be explored. PMID:18097780

    Long-term outcomes for women with a diagnosis of human epidermal growth factor receptor 2 (HER2)-driven early-stage breast cancer have significantly improved since the advent of HER2-targeted therapy. Although the first studies in the early-stage setting focused on the adjuvant use of trastuzumab plus chemotherapy, clinical trials increasingly are using a neoadjuvant design to evaluate novel HER2-targeted therapies. Neoadjuvant therapy downstages locally advanced breast cancer, improves rates of breast conservation, and provides information regarding the responsiveness of a cancer to systemic therapy; in addition, studies have shown that the pathologic response to neoadjuvant therapy is correlated with event-free and overall survival. Given these advantages, multiple studies of neoadjuvant therapy, several of which have reported longer-term outcomes, have been conducted to evaluate HER2-targeted therapies. This review summarizes available data from prior and ongoing neoadjuvant trials in HER2-positive breast cancer, focusing on those studies that have reported not only pathologic response rates but also event-free, disease-free, and/or overall survival. The long-term outcomes associated with the achievement of a pathologic complete response are explored, and the comparisons of pathologic complete response rates, event-free survival, and overall survival reported for different HER2-targeted regimens are reviewed.

    Background The purpose of this analysis was to compare long-term urinary, bowel, and sexual function after radical prostatectomy or external-beam radiation therapy. Methods The Prostate Cancer Outcomes Study (PCOS) enrolled 3533 men in whom prostate cancer had been diagnosed in 1994 or 1995. The current cohort comprised 1655 men in whom localized prostate cancer had been diagnosed between the ages of 55 and 74 years and who had undergone either surgery (1164 men) or radiotherapy (491 men). Functional status was assessed at baseline and at 2, 5, and 15 years after diagnosis. We used multivariable propensity scoring to compare functional outcomes according to treatment. Results Patients undergoing prostatectomy were more likely to have urinary incontinence than were those undergoing radiotherapy at 2 years (odds ratio, 6.22; 95% confidence interval [CI], 1.92 to 20.29) and 5 years (odds ratio, 5.10; 95% CI, 2.29 to 11.36). However, no significant between-group difference in the odds of urinary incontinence was noted at 15 years. Similarly, although patients undergoing prostatectomy were more likely to have erectile dysfunction at 2 years (odds ratio, 3.46; 95% CI, 1.93 to 6.17) and 5 years (odds ratio, 1.96; 95% CI, 1.05 to 3.63), no significant between-group difference was noted at 15 years. Patients undergoing prostatectomy were less likely to have bowel urgency at 2 years (odds ratio, 0.39; 95% CI, 0.22 to 0.68) and 5 years (odds ratio, 0.47; 95% CI, 0.26 to 0.84), again with no significant between-group difference in the odds of bowel urgency at 15 years. Conclusions At 15 years, no significant relative differences in disease-specific functional outcomes were observed among men undergoing prostatectomy or radiotherapy. Nonetheless, men treated for localized prostate cancer commonly had declines in all functional domains during 15 years of follow-up. (Funded by the National Cancer Institute.) PMID:23363497

    Purpose: To explore very-long-term mortality from ischemic heart disease (IHD) after locoregional radiation therapy of breast cancer (BC) in relation to degree of hypofractionation and other treatment variables. Methods and Materials: Two hypofractionated regimens used for locoregional radiation therapy for BC from 1975 to 1991 were considered. Patients received 4.3 Gy × 2/week (10 fractions; target dose 43 Gy; n=1107) or 2.5 Gy × 5/week (20 fractions; target dose 50 Gy; n=459). To estimate cardiac doses, radiation fields were reconstructed in a planning system. Time to death from IHD was the endpoint, comparing the groups with each other and with age-matched, cancer-free control individuals, modeled with the Cox proportional hazards model. Results: Patients given 4.3 Gy × 10 had an increased risk of dying of IHD compared with both the 2.5 Gy group (hazard ratio [HR] = 2.37; 95% confidence interval [CI]: 1.06-5.32; P=.036) and the control group (HR = 1.59; 95% CI: 1.13-2.23; P=.008). Photon beams for parasternal fields gave an increased risk of dying of IHD compared with electron beams (HR = 2.56; 95% CI: 1.12-5.84; P=.025). Multivariate analysis gave an increased risk for the 4.3-Gy versus 2.5-Gy regimen with borderline significance (HR = 2.90; 95% CI: 0.97-8.79; P=.057) but not for parasternal irradiation. Conclusions: The degree of hypofractionation and parasternal photon beams contributed to increased cardiac mortality in this patient cohort. Differences emerged after 12 to 15 years, indicating the need of more studies with observation time of 2 decades.

    AIM: To retrospectively analyze factors affecting the long-term survival of patients with pancreatic cancer who underwent pancreatic resection. METHODS: From January 2000 to December 2011, 195 patients underwent pancreatic resection in our hospital. The prognostic factors after pancreatic resection were analyzed in all 195 patients. After excluding the censored cases within an observational period, the clinicopathological characteristics of 20 patients who survived ≥ 5 (n = 20) and < 5 (n = 76) years were compared. For this comparison, we analyzed the patients who underwent surgery before June 2008 and were observed for more than 5 years. For statistical analyses, the log-rank test was used to compare the cumulative survival rates, and the χ2 and Mann-Whitney tests were used to compare the two groups. The Cox-Hazard model was used for a multivariate analysis, and P values less than 0.05 were considered significant. A multivariate analysis was conducted on the factors that were significant in the univariate analysis. RESULTS: The median survival for all patients was 27.1 months, and the 5-year actuarial survival rate was 34.5%. The median observational period was 595 d. With the univariate analysis, the UICC stage was significantly associated with survival time, and the CA19-9 ≤ 200 U/mL, DUPAN-2 ≤ 180 U/mL, tumor size ≤ 20 mm, R0 resection, absence of lymph node metastasis, absence of extrapancreatic neural invasion, and absence of portal invasion were favorable prognostic factors. The multivariate analysis showed that tumor size ≤ 20 mm (HR = 0.40; 95%CI: 0.17-0.83, P = 0.012) and negative surgical margins (R0 resection) (HR = 0.48; 95%CI: 0.30-0.77, P = 0.003) were independent favorable prognostic factors. Among the 96 patients, 20 patients survived for 5 years or more, and 76 patients died within 5 years after operation. Comparison of the 20 5-year survivors with the 76 non-survivors showed that lower concentrations of DUPAN-2 (79.5 vs 312.5 U/mL, P

    Study Design Prospective study. Purpose The aim of the study was to present long-term results from a 10-year follow-up after endoscopic lumbar discectomy (ELD) by "Destandau's technique". Overview of Literature Endoscopic disc surgery by Destandau's technique using ENDOSPINE Karl Storz system is a relatively new technique. It was introduced in 1993. It has been gaining popularity among the spine surgeons, as it is attractive for small skin incision and allows a gentle and excellent tissue dissection with excellent visualization. Many authors have published results of their own studies; however, in all these studies the long-term follow up of the patients has not been emphasized. Methods A total of 21 patients selected on basis of strict inclusion criteria's underwent ELD from November 2004 to March 2005. Surgery outcome was assessed by using "Prolo's Anatomic-Functional-Economic Rating System" (1986). Patients were followed up to 10 years. In addtion, we compared the results of our study with other studies. Results Outcomes were excellent in 17 patients (80.95%), good in 3 (14.28%) and fair in 1 (4.78%), with no patients having a poor result. In our study, 19 patients (90.47%) were able to resume their previous works/jobs, and only 2 (9.52%) needed to change their jobs for lighter work. No patient retired from his or her previous daily routine following the operation. Conclusions The initial and long-term results are very good for endoscopic lumbar discectomy by Destandau's technique. In properly selected patients it is a safe and minimally invasive technique, and we recommend ELD in properly selected patients. PMID:27114770

    Purpose: To assess the impact of dose escalation of radiotherapy on quality of life (QoL) in prostate cancer patients. Patients and Methods: Three hundred prostate cancer patients participating in the Dutch randomized trial (CKTO 69-10) comparing 68 Gy with 78 Gy were the subject of this analysis. These patients filled out the SF-36 QoL questionnaire before radiotherapy (baseline) and 6, 12, 24, and 36 months thereafter. Changes in QoL over time of {>=}10 points were considered clinically relevant. Repeated-measures regression analyses were applied to estimate and test the QoL changes over time, the differences between the two arms, and for association with a number of covariates. Results: At 3-year follow-up, the summary score physical health was 73.2 for the 68-Gy arm vs. 71.6 for the 78-Gy arm (p = 0.81), and the summary score mental health was 76.7 for the 68-Gy arm vs. 76.1 for the 78-Gy arm (p = 0.97). Statistically significant (p < 0.01) deterioration in QoL scores over time was registered in both arms in six scales. The deterioration over time was more pronounced in the high-dose arm for most scales. However, clinically relevant deterioration (>10 points) was seen for only two scales. None of the tested covariates were significantly correlated with QoL scores. Conclusion: Dose escalation did not result in significant deterioration of QoL in prostate cancer patients. In both randomization arms, statistically significant decreases in QoL scores over time were seen in six scales. The deterioration of QoL was more pronounced in the physical than in the mental health domain and in some scales more in the high- than in the low-dose arm, but the differences between arms were not statistically significant.

    One thousand one hundred and thirty-six patients surviving for more than five years after radiotherapy were studied. The important prognostic factors are: lesion less than 5 cm in length, lesion located in the upper-third segment and lesion that is radiosensitive. The radiation dose given to long term survivors varies greatly, i.e., 2700 to 9300 rad. Yet, for the sensitive type of lesion, doses lower than 5000 rad could also effect a cure. The delivery of an optimum dose determined by serial examinations during radiotherapy could improve the result of treatment. For local recurrent lesions, the value of a second course of radiation is extremely limited and surgery is the only means to offer a cure. For metastasis in the lymph nodes, radiation offers some hope of cure, although the long term outcome may not be satisfactory. For second primary cancer of the esophagus, aggressive radiation still gives encouraging results.

    Biliary Atresia (BA) is a rare disorder. It is the leading cause of cholestasis in the newborn period, and the single most frequent indication for Orthotopic Liver Transplantation (OLT) in children. Early diagnosis of BA is critical for optimal intervention. Our objective in the current study is to compare the results of our center to those reported in the literature, in terms of incidence of BA, age at diagnosis, rates of OLT and long term survival after operation. A secondary objective is to seek differences between the Jewish and non-Jewish population. The study included newborns with BA who were treated in Soroka University Medical Center between the years 1980-2007. The sources of information included medical charts, operation reports, and follow-up tests and visits. The comparison between the results of our study and those accepted in the western world, and between the two populations, was made using proportion test for two independent samples. The long term results were analyzed using the Kaplan Meier method. Overall, 29 infants with BA were treated: 16 were Jewish and 13 non-Jewish; 15 (52%) males and 14 (48%) females. The incidence rate of BA was 0.9 per 10,000 live births. The average age at operation was 58 + 23 days (20 to 115). Fifteen (51%) of the patients are alive today: 10 with their native liver and 5 after OLT. Two children who underwent OLT died 1-3 months after the transplantation. Nine (31%) patients died due to end stage liver disease and its complications, without OLT. Three of the patients were lost to follow-up. The OLT rates in the Jewish population were 31% compared to 15% in the non-Jewish population (p = 0.41). The long term results of our center meet the reported results from other parts of the world, with no significant difference between the two populations. PMID:19485273

    The continuing search for a cure for cancer has lead to more aggressive therapies as new agents are developed with largely unknown late complications. Standard therapy for the majority of cancers today, following surgery, often consists of combinations of high doses of radiation and multi-drug therapy. Compared with exposures experienced by atomic bomb survivors, cancer survivors have been exposed to higher doses of partial body irradiation and combination chemotherapy over longer periods. Thus, cancer survivors provide a model system with which to evaluate the long-term effects on the human organism of high doses of agents known to damage DNA. Five-year survival after cancer diagnosis is now greater than 56%; more than 5 million Americans are considered cured of cancer. However, the late complications of cancer in long-term survivors has been poorly evaluated, especially in adults, and little is known of the most troubling possibility, that is, that the effects of cancer treatments could be passed on to the next generation. What little we know comes from studies of at most 5,000 survivors of childhood cancer, treated decades ago. So far, results are reassuring that with the means now available, we cannot detect clinical evidence of heritable damage. However, reproductive effects, including infertility, are common consequences of cancer therapy and may represent germ cell damage. We are just in the infancy of studies of germ cell mutagenesis in cancer survivors. The relatively small numbers of survivors, and the few types of exposures studied so far, provide only limited grounds for reassurance. More comprehensive, properly designed, studies of modern new agents are urgently need. PMID:10331521

    Evidence as to the value of preoperative carcinoembryonic antigen (CEA) in guiding treatment for patients with colorectal cancer is conflicting. The aim of this prospective study was to investigate the value of preoperative CEA in predicting tumour factors of proven prognostic value and long-term survival in patients undergoing surgery for colorectal cancer. Preoperative serum CEA, tumour ploidy, stage and grade were ascertained in 277 patients undergoing colorectal cancer surgery. This cohort of patients were followed up for a minimum of 5 years, or until death, in a dedicated colorectal clinic. Patients with an elevated CEA had a 5 year survival of 39%. This increased to 57% if the CEA was normal (P=0.001). The proportion of patients with a raised CEA increased with a more advanced tumour stage (P < 0.000001) and a poorly differentiated tumour grade (P < 0.005). Once stage had been controlled for, CEA was not a predictor of survival. No relationship between tumour ploidy and CEA was found. In conclusion, a raised preoperative serum CEA is likely to be associated with advanced tumour stage and poor long-term survival, compared with patients with a normal value. PMID:9823977

    Background: To compare long term results of laparoscopic and endoscopic exploration of common bile duct, to assess post-procedure quality of life. Materials and Methods: From September 1992 to August 2003, we performed 4058 cholecystectomies, out of which 479 (11.80%) patients had choledocholithiasis. There were 163 males and 316 females. Mean age was 63.65 ± 5.5 years. These patients were put in two groups. In the first group of 240 patients, a majority of patients underwent two-stage procedures. ERCP/ES was performed in 210 (87.50%) cases. In the second group of 239 patients, a majority of patients underwent single-stage procedures. ERCP/ES was done in 32 (13.38%) cases. Results: Mortality was zero in both groups. Morbidity was 15.1% in first group and 7.5% in second group. Mean hospital stay was 11.7 ± 3.2 days in first group and 6.2 ± 2.1 days in second group. Average operative time was 95.6 ± 20 minutes in first group and 128.4 ± 32 minutes in second group. Completed questionnaires received from 400 (83.50%) patients revealed better long-term results in the second group. Clinical features of low-grade cholangitis were seen in 20% of patients who underwent ES. Hence the post-procedure quality of life in patients who underwent single-stage procedures was definitely much better, because of minimal damage of sphincter of Oddi. Conclusions: Single-stage laparoscopic operations provide better results and shorter hospital stay. Damage to sphincter of Oddi should be minimal, to avoid long-term low-grade cholangitis. In young patients, the operation of choice should be single-stage laparoscopic procedure with absolutely no damage to sphincter of Oddi. PMID:21170222

    Purpose: To investigate conventional prognostic factors for ipsilateral breast tumor recurrence (IBTR), distant metastasis (DM), and survival after breast-conserving therapy (BCT) in screen-detected and symptomatic cases on surveillance up to 25 years. Patients and Methods: A total of 1812 consecutive patients in three cohorts (1981-1989, 1990-1992, and 1993-1998) with T12N01M0 invasive breast cancer were treated with BCT (median follow-up, 14 years). Tumor type and grade were reviewed by a single pathologist. Hormone receptor status was measured by immunohistochemistry on tissue microarrays. A Cox proportional hazards model was used to assess independent prognostic variables for relapse and survival. Results: A total of 205 IBTR occurred, with 5-, 10-, 15-, and 20-year actuarial relapse rates of 4.5% (95% confidence interval [CI] 3.35-5.5%), 8.4% (95% CI 7.1-9.8%), 14.1% (95% CI 12.0-16%), and 17.4% (95% CI 14.5-20.2%). Number of nodes, young age, pathologic tumor size, and multifocality were significant factors for IBTR. Three hundred seventy-eight patients developed DM. The actuarial metastatic rate was 12% at 5 years and 17.9% at 10 years. Young age, number of positive nodes, pathologic tumor size, and tumor grade were significant factors for DM relapse. When conventional prognostic indices were taken into account screen-detected cancers showed no improvement in overall relapse or survival rate compared with symptomatic cases but did show a reduced risk of DM after IBTR. After 10 years IBTR relapse continued at a constant rate of 0.87% per annum. Conclusions: The Edinburgh BCT series has shown that screen-detected invasive breast cancers do not have significantly different clinical outcomes compared with symptomatic cases when pathologic risk factors are taken into account. This suggests that these patients be managed in a similar way.

OBJECTIVE: To confirm the safety and utility of PHDPE by analyzing aesthetic outcomes and assessing the frequency of complication related to PHDPE in a large, population-based, long-term follow-up study. METHODS: A total of 151 patients who had undergone septoplasty and/or functional rhinoplasty using PHDPE were enrolled. PHDPE sheets were used for diverse purposes such as septal extension graft, spreader graft, columellar strut or dorsal augmentation graft. After a long-term follow-up period (mean [± SD] 39.5±27.8 months; range six to 101 months), postoperative aesthetic outcome was evaluated objectively (by independent surgeons) and subjectively (patient self-report). Complications related to PHDPE were estimated through review of medical records. RESULTS: The most common use of the PHDPE graft was for septal extension (n=80 [42.6%]) and spreader graft (n=58 [30.9%]). Results of aesthetic evaluation by surgeons were excellent in 61 cases (40.4%), good in 54 (35.8%) and fair in 34 (22.5%). According to patient self-report, 100 were ‘satisfied’ (66.2%) and 36 rated their new profile as ‘better than the preoperative profile’ (23.8%). Complications were reported in six cases (4.0% [five cases of extrusion and one case of infection]). All complications were resolved after the surgical removal of PHDPE sheets under local anesthesia. CONCLUSION: The present study demonstrated that PHDPE could be used in functional primary rhinoplasty with excellent long-term aesthetic results and safety. PMID:25152641

    AIM To evaluate the long-term efficacy and safety results of viscocanalostomy and phacoviscocanalostomy. METHODS The charts of 49 glaucoma patients who underwent viscocanalostomy or phacoviscocanalostomy surgery between February 1999 and August 2004 were reviewed retrospectively. Thirty-one eyes of 21 glaucoma patients who underwent filtering procedure with a postoperative follow-up of at least 5y were included in the study. Results of complete ophthalmologic examinations were recorded and statistically analyzed. Long-term surgical outcome was defined as an overall success when intraocular pressure (IOP) was found as ≤20 mm Hg with or without antiglaucomatous medication at the last follow-up visit, while it was defined as a complete success when IOP was measured ≤20 mm Hg without antiglaucomatous medication. RESULTS Mean age was 68.1±9.6y (range: 32-81y). Mean follow-up time was 101.5±27.3mo (range: 60-144mo). Viscocanalostomy was performed in 8 eyes (25.8%) and phacoviscocanalostomy was performed in 23 eyes (74.2%). The mean preoperative IOP was 23.1±7.6 mm Hg with 2.1±1.0 medications, while mean IOP was 16.8±3.8 mm Hg with 0.9±1.1 medication at the last follow-up visit. Both the IOP decrease and the reduction in the antiglaucomatous medication were statistically significant (P<0.001 and P<0.001). No case required further glaucoma surgery. Overall success and complete success were found as 87.1% and 51.6%, respectively. Complete success rate was statistically higher in phacoviscocanalostomy group compared with the viscocanalostomy group (P=0.031), however there was no significant difference in overall success rate between two groups (P=0.072). CONCLUSION Both viscocanalostomy and phacoviscocanalostomy provide good IOP reduction in the long-term period. PMID:26682166

    Background We evaluated early and long-term results after heart transplantation (HTPL). Methods One hundred five consecutive patients (male:female=80:25) who underwent HTPL between 1994 and 2013 were enrolled. Based on the changes in immunosuppressive regimen, the study patients were divided into two groups. Early and long-term clinical outcomes were evaluated and compared between the patients who underwent HTPL before (group E, n=41) and after July 2009 (group L, n=64). The group L patients were older (p<0.001), had higher incidence of hypertension (p=0.001) and chronic kidney disease (p<0.001), and more frequently needed preoperative mechanical ventilation (p=0.027) and mechanical circulatory support (p=0.014) than the group E patients. Results Overall operative mortality was 3.8%, and postoperative morbidities included acute kidney injury (n=31), respiratory complications (n=16), reoperation for bleeding (n=15) and wound complications (n=10). There were no significant differences in early results except acute kidney injury between group E and group L patients. Overall survival rates at 1, 5, and 10 years were 83.8%, 67.7%, and 54.9%, respectively, with no significant difference between the two patient groups. Rejection-free rates at 1 and 5 years were 63.0% and 59.7%, respectively; rates were significantly higher in group L than in group E (p<0.001). Conclusion Despite increased preoperative comorbidities, group L patients showed similar early and long-term outcomes and significantly higher rejection-free rates when compared with group E patients.

    PurposeTo evaluate the safety, efficacy, and long-term results of endovascular stent graft placement for ureteroarterial fistula (UAF).MethodsWe retrospectively analyzed stent graft placement for UAF performed at our institution from 2004 to 2012. Fistula location was assessed by contrast-enhanced computed tomography (CT) and angiography, and freedom from hematuria recurrence and mortality rates were estimated.ResultsStent graft placement for 11 UAFs was performed (4 men, mean age 72.8 {+-} 11.6 years). Some risk factors were present, including long-term ureteral stenting in 10 (91 %), pelvic surgery in 8 (73 %), and pelvic radiation in 5 (45 %). Contrast-enhanced CT and/or angiography revealed fistula or encasement of the artery in 6 cases (55 %). In the remaining 5 (45 %), angiography revealed no abnormality, and the suspected fistula site was at the crossing area between urinary tract and artery. All procedures were successful. However, one patient died of urosepsis 37 days after the procedure. At a mean follow-up of 548 (range 35-1,386) days, 4 patients (36 %) had recurrent hematuria, and two of them underwent additional treatment with secondary stent graft placement and surgical reconstruction. The hematuria recurrence-free rates at 1 and 2 years were 76.2 and 40.6 %, respectively. The freedom from UAF-related and overall mortality rates at 2 years were 85.7 and 54.9 %, respectively.ConclusionEndovascular stent graft placement for UAF is a safe and effective method to manage acute events. However, the hematuria recurrence rate remains high. A further study of long-term results in larger number of patients is necessary.

    In a retrospective cohort study of survivors of cancer and of controls, we estimated the risk of infertility after treatment for cancer during childhood or adolescence. We interviewed 2283 long-term survivors of childhood or adolescent cancer diagnosed in the period from 1945 through 1975, who were identified at five cancer centers in the United States. Requirements for admission to the study were diagnosis before the age of 20, survival for at least five years, and attainment of the age of 21. In addition, 3270 controls selected from among the survivors' siblings were interviewed. Cox regression analysis showed that cancer survivors who married and were presumed to be at risk of pregnancy were less likely than their sibling controls to have ever begun a pregnancy (relative fertility, 0.85; 95 percent confidence interval, 0.78 to 0.92). Radiation therapy directed below the diaphragm depressed fertility in both sexes by about 25 percent. Chemotherapy with alkylating agents, with or without radiation to sites below the diaphragm, was associated with a fertility deficit of about 60 percent in the men. Among the women, there was no apparent effect of alkylating-agent therapy administered alone (relative fertility, 1.02) and only a moderate fertility deficit when alkylating-agent therapy was combined with radiation below the diaphragm (relative fertility, 0.81). Relative fertility in the survivors varied considerably according to sex, site of cancer, and type of treatment; these factors should be taken into consideration in counseling survivors about the long-term consequences of disease.

  10. Could the Geminid meteoroid stream be the result of long-term thermal fracture?

    2015-01-01

    The previous models by Ryabova have shown that the Geminid meteoroid stream has a cometary origin, so asteroid (3200) Phaethon (the Geminids' parent body) is probably a dead comet. Recently (in 2009 and 2012) some weak activity was observed (Jewitt and Li, 2010, 2013), but it was not a cometary activity. Recurrent brightening of Phaethon at perihelion could be the result of thermal fracture and decomposition. In this study we model the long term dust release from Phaethon based on this mechanism. It is unlikely that the Geminid meteoroid stream (or its low-active wide component) was generated by long-time thermal fracture.

    Analyses and results are reported of a test program to establish the effects of long-term (10 years or more) contact of materials with nitrogen textroxide MON-1 for the purpose of designing chemical propulsion system components which can be used for current as well as future planetary spacecraft. The test materials included aluminum alloy, corrosion-resistant steel, titanium alloy, and nickel. The weight and appearance of each specimen were observed, including the presence of deposits, etching, pitting, and cracking. Aluminum alloy and steel were rated satisfactory with minor reservations, titanium alloy was satisfactory, and nickel was unsatisfactory. Criteria for ratings are shown.

    Interim results from a number of ongoing, long-term environmental effects programs for composite materials are reported. The flight service experience is evaluated for 142 composite aircraft components after more than five years and one million successful component flight hours. Ground-based outdoor exposures of composite material coupons after 3 years of exposure at five sites have reached equilibrium levels of moisture pickup which are predictable. Solar ultraviolet-induced material loss is discussed for these same exposures. No significant degradation has been observed in residual strength for either stressed or unstressed specimens, or for exposures to aviation fuels and fluids.

  13. Long-term effects of chemical disasters. Lessons and results from Seveso.

    Fourteen years after its occurrence (10 July 1976) the Seveso accident is still considered the prototype for chemical disasters. Thousands of persons were potentially exposed to dioxin after an uncontrolled development during the manufacture of trichlorophenol in a chemical plant. The most evident adverse health effect ascertained was chloracne (193 cases). Other reversible early effects noted were peripheral neuropathy and liver enzyme induction. The ascertainment of other, possibly severe sequelae of dioxin exposure (e.g., birth defects) was hampered by inadequate information; however, generally, no increased risks were evident. Mortality studies shed some light on the long-term effects. An unusual cardiovascular mortality pattern was reported in the exposed population. Cancer mortality findings after 10 years do not allow firm conclusions to be drawn, but are suggestive of a departure from expectations for certain types of cancer; the ongoing cancer incidence study will further explore these hypotheses. A variety of lessons were learned after this accident, and some have been incorporated into international regulations regarding industrial activities and environmental safety. This paper focuses on lessons relevant to the design and conduct of health studies in the aftermath of chemical disasters, with special emphasis given to identification of the study population, ascertainment of individual exposure, and attainment of information.

    Background: The Over-The-Scope Clip (OTSC®, Ovesco Endoscopy GmbH, Tübingen, Germany) is an innovative clipping device that provides a strong tissue grasp and compression without provoking ischemia or laceration. In this retrospective study we evaluated immediate and long-term success rates of OTSC deployment in various pathologies of the gastrointestinal (GI) tract. Methods: A total of 45 patients (35 female, 10 male) with an average age of 56 years old (range, 24–90 years) were treated with an OTSC for GI defects resulting from a diagnostic or interventional endoscopic procedure (acute setting group) or for fistula following abdominal surgery (chronic setting group). All procedures were performed with CO2 insufflation. Results: From January 2012 to December 2015 a total of 51 OTSCs were delivered in 45 patients for different kinds of GI defects. Technical success was always achieved in the acute setting group with an excellent clip adherence and a clinical long-term success rate of 100% (15/15). Meanwhile, considering the chronic setting group, technical success was achieved in 50% of patients with a long-term clinical success of 37% (11/30); two minor complications occurred. A total of three patients died due to causes not directly related to clip deployment. Overall clinical success rate was achieved in 58% cases (26/45 patients). A mean follow-up period of 17 months was accomplished (range, 1–36 months). Conclusion: OTSC deployment is an effective and minimally-invasive procedure for GI defects in acute settings. It avoids emergency surgical repair and it allows, in most cases, completion of the primary endoscopic procedure. OTSC should be incorporated as an essential technique of today’s modern endoscopic armamentarium in the management of GI defects in acute settings. OTSCs were less effective in cases of chronic defects. PMID:27582884

    OBJECTIVE—To analyse the long term results of mechanical prostheses for treating active infective endocarditis.
DESIGN—Prospective cohort study of a consecutive series of patients diagnosed with infective endocarditis and operated on in the active phase of the infection for insertion of a mechanical prosthesis.
SETTING—Tertiary referral centre in a metropolitan area.
RESULTS—Between 1975 and 1997, 637 cases of infective endocarditis were diagnosed in the centre. Of these, 436 were left sided (with overall mortality of 20.3%). Surgical treatment in the active phase of the infection was needed in 141 patients (72% native, 28% prosthetic infective endocarditis). Mechanical prostheses were used in 131 patients. Operative mortality was 30.5% (40 patients). Ninety one survivors were followed up prospectively for (mean (SD)) 5.4 (4.5) years. Thirteen patients developed prosthetic valve dysfunction. Nine patients suffered reinfection: four of these (4%) were early and five were late. The median time from surgery for late reinfection was 1.4 years. During follow up, 12 patients died. Excluding operative mortality, actuarial survival was 86.6% at five years and 83.7% at 10 years; actuarial survival free from death, reoperation, and reinfection was 73.1% at five years and 59.8% at 10 years.
CONCLUSIONS—In patients surviving acute infective endocarditis and receiving mechanical prostheses, the rate of early reinfection compares well with reported results of homografts. In addition, prosthesis dysfunction rate is low and long term survival is good. These data should prove useful for comparison with long term studies, when available, using other types of valve surgery in active infective endocarditis.

    OBJECTIVES: To define the effects of long-term thyroxine treatment upon heart rate, blood pressure, left ventricular systolic function, and left ventricular size, as well as indices of autonomic function, and to compare findings with those in patients with thyrotoxicosis before and during treatment. DESIGN: Cross sectional study of patients prescribed thyroxine long term (n = 11), patients with thyrotoxicosis studied at presentation (n = 23), compared with controls (n = 25); longitudinal study of patients with thyrotoxicosis studied at presentation and serially after beginning antithyroid drug treatment (n = 23). METHODS: 24 h ambulatory monitoring of pulse and blood pressure, echocardiography, forearm plethysmography, and autonomic function tests. RESULTS: Long-term thyroxine treatment in doses that reduced serum thyrotrophin to below normal had no effect on blood pressure, heart rate, left ventricular systolic function or stroke volume index, but was associated with an 18.4% increase in left ventricular mass index (mean (SEM) 101.9 (3.09) g/m2 v controls 86.1 (4.61), P < 0.01). Thryoxine treatment, like thyrotoxicosis, had no effect on tests of autonomic function. Untreated thyrotoxicosis resulted in pronounced changes in systolic and diastolic blood pressure and an increase in heart rate during waking and sleep. Patients with thyrotoxicosis at presentation had an increase in left ventricular systolic function (ejection fraction 70.5 (1.66)% v 65.4 (1.79), P < 0.01; fractional shortening 40.4 (1.54)% v 35.6 (1.46), P < 0.01), increased stroke volume index (45.9 (2.4) ml/m2 v 36.6 (1.7), P < 0.001), and an increase in forearm blood flow, and decrease in vascular resistance. They had a similar degree of left ventricular hypertrophy to that associated with thyroxine treatment (99.3 (4.03) g/m2); all changes were corrected within 2 months by antithyroid drugs. CONCLUSIONS: The development of left ventricular hypertrophy in patients receiving thyroxine in the absence

    Rescuing patients in severe cardiac failure with extracorporeal support remains challenging. The Gyro pump is a centrifugal blood pump and was now used for cardiopulmonary bypass, although it was originally developed for long-term cardiac assist. Little is known about clinical experiences using this pump. Here, we report on the clinical results of long-term extracorporeal life support for over 4 days using the Gyro pump with Excelung, a hollow fiber oxygenator coated with silicone and heparin. Seven patients underwent extracorporeal life support with 15 pump and oxygenator combinations. Gyro and Excelung were used for venoarterial extracorporeal support in six patients and for right ventricular support in one patient. Patient characteristics, pump driving conditions, and blood chemistry were obtained retrospectively. All pumps were subsequently disassembled and examined macroscopically, with 6 of 15 pumps also examined by scanning electron microscopy (SEM). The patient mortality rate was 57.1%. Mean duration of support was 10.5 ± 7.2 days per pump and oxygenator combination. Lactate dehydrogenase and aspartate aminotransferase were generally maintained below 1000 and 100 IU/L, respectively, after the first 4 days of pump driving. Thrombi were found in two pumps, one used without anticoagulation and the other driven at a very slow rotational speed. SEM revealed no wear in the male bearings and very low wear and deformation (0.02 ± 0.03 mm) in the female bearings. The combination of Gyro and Excelung may be applicable for long-term biventricular and right ventricular support, although proper anticoagulation should be administrated to avoid thrombus formation inside the pump.

    Background In this study we aimed to evaluate the long-term outcome of diaphragmatic plication for symptomatic unilateral diaphragm paralysis. Methods Thirteen patients who underwent unilateral diaphragmatic plication (2 patients had right, 11 left plication) between January 2003 and December 2006 were evaluated. One patient died postoperatively due to sepsis. The remaining 12 patients [9 males, 3 females; mean age 60 (36-66) years] were reevaluated with chest radiography, flouroscopy or ultrasonography, pulmonary function tests, computed tomography (CT) or magnetic resonance imaging (MRI), and the MRC/ATS dyspnea score at an average of 5.4 (4-7) years after diaphragmatic plication. Results The etiology of paralysis was trauma (9 patients), cardiac by pass surgery (3 patients), and idiopathic (1 patient). The principle symptom was progressive dyspnea with a mean duration of 32.9 (22-60) months before surgery. All patients had an elevated hemidiaphragm and paradoxical movement radiologically prior to surgery. There were partial atelectasis and reccurent infection of the lower lobe in the affected side on CT in 9 patients. Atelectasis was completely improved in 9 patients after plication. Preoperative spirometry showed a clear restrictive pattern. Mean preoperative FVC was 56.7 ± 11.6% and FEV1 65.3 ± 8.7%. FVC and FEV1 improved by 43.6 ± 30.6% (p < 0.001) and 27.3 ± 10.9% (p < 0.001) at late follow-up. MRC/ATS dyspnea scores improved 3 points in 11 patients and 1 point in 1 patient at long-term (p < 0.0001). Eight patients had returned to work at 3 months after surgery. Conclusions Diaphragmatic plication for unilateral diaphragm paralysis decreases lung compression, ensures remission of symptoms, and improves quality of life in long-term period. PMID:21078140

    Objective. To investigate the long-term (ie, 6-year) impact of a required remake vs an optional remake on student performance in a compounding laboratory course in which students’ compounded preparations were analyzed. Methods. The analysis data for several preparations made by students were compared for differences in the analyzed content of the active pharmaceutical ingredient (API) and the number of students who successfully compounded the preparation on the first attempt. Results. There was a consistent statistical difference in the API amount or concentration in 4 of the preparations (diphenhydramine, ketoprofen, metoprolol, and progesterone) in each optional remake year compared to the required remake year. As the analysis requirement was continued, the outcome for each preparation approached and/or attained the expected API result. Two preparations required more than 1 year to demonstrate a statistical difference. Conclusion. The analytical assessment resulted in a consistent, long-term improvement in student performance during the 5-year period after the optional remake policy was instituted. Our assumption is that investment in such an assessment would result in a similar benefits at other colleges and schools of pharmacy. PMID:26056402

    Purpose: To present the largest series of prostate cancer brachytherapy patients treated with modern brachytherapy techniques and postimplant day 0 dosimetric evaluation. Methods and Materials: Between April 1995 and July 2006, 1,656 consecutive patients were treated with permanent interstitial brachytherapy. Risk group stratification was carried out according to the Mt. Sinai guidelines. Median follow-up was 7.0 years. The median day 0 minimum dose covering at least 90% of the target volume was 118.8% of the prescription dose. Cause of death was determined for each deceased patient. Multiple clinical, treatment, and dosimetric parameters were evaluated for impact on the evaluated survival parameters. Results: At 12 years, biochemical progression-free survival (bPFS), cause-specific survival (CSS), and overall survival (OS) for the entire cohort was 95.6%, 98.2%, and 72.6%, respectively. For low-, intermediate-, and high-risk patients, bPFS was 98.6%, 96.5%, and 90.5%; CSS was 99.8%, 99.3%, and 95.2%; and OS was 77.5%, 71.1%, and 69.2%, respectively. For biochemically controlled patients, the median posttreatment prostate-specific antigen (PSA) concentration was 0.02 ng/ml. bPFS was most closely related to percent positive biopsy specimens and risk group, while Gleason score was the strongest predictor of CSS. OS was best predicted by patient age, hypertension, diabetes, and tobacco use. At 12 years, biochemical failure and cause-specific mortality were 1.8% and 0.2%, 5.1% and 2.1%, and 10.4% and 7.1% for Gleason scores 5 to 6 and 7 and {>=}8, respectively. Conclusions: Excellent long-term outcomes are achievable with high-quality brachytherapy for low-, intermediate-, and high-risk patients. These results compare favorably to alternative treatment modalities including radical prostatectomy.

    Purpose: To evaluate the risk of second cancers after cervical cancer treated with radiotherapy for Asian populations. Methods and Materials: We reviewed 2,167 patients with cervical cancer undergoing radiotherapy between 1961 and 1986. Intracavitary brachytherapy was performed with high-dose rate source (82%) or low-dose rate source (12%). Relative risk (RR), absolute excess risk (AR), and cumulative risk of second cancer were calculated using the Japanese disease expectancy table. For 1,031 patients, the impact of smoking habit on the increasing risk of second cancer was also evaluated. Results: The total number of person-years of follow-up was 25,771, with 60 patients being lost to follow-up. Among the 2,167 patients, 1,063 (49%) survived more than 10 years. Second cancers were observed in 210 patients, representing a significant 1.2-fold risk (95% confidence interval [CI], 1.1-1.4) of developing second cancer compared with the general population, 1.6% excess risk per person per decade of follow-up, and elevating cumulative risk up to 23.8% (95% CI, 20.3-27.3) at 30 years after radiotherapy. The RR of second cancer was 1.6-fold for patients with the smoking habit and 1.4-fold for those without. Conclusions: Small but significant increased risk of second cancer was observed among Japanese women with cervical cancer mainly treated with high-dose rate brachytherapy. Considering the fact that about half of the patients survived more than 10 years, the benefit of radiotherapy outweighs the risk of developing second cancer.

    AIM: To compare the results after revision of primary vertical banded gastroplasty (Re-VBG) and conversion to sleeve gastrectomy (cSG) or gastric bypass (cRYGB). METHODS: In this retrospective single-center study, all patients with a failed VBG who underwent revisional surgery were included. Medical charts were reviewed and additional postal questionnaires were sent to update follow-up. Weight loss, postoperative complications and long-term outcome were assessed. RESULTS: A total 152 patients were included in this study, of which 21 underwent Re-VBG, 16 underwent cSG and 115 patients underwent cRYGB. Sixteen patients necessitated a second revisional procedure. No patients were lost-to-follow-up. Two patients deceased during the follow-up period, 23 patients did not return the questionnaire. Main reasons for revision were dysphagia/vomiting, weight regain and insufficient weight loss. Excess weight loss (%EWL) after Re-VBG, cSG and cRYGB was, respectively, 45%, 57% and 72%. Eighteen patients (11.8%) reported postoperative complications and 27% reported long-term complaints. CONCLUSION: In terms of additional weight loss, postoperative complaints and reintervention rate, Roux-en-Y gastric bypass seems feasible as a revision for a failed VBG. PMID:27022451

A considerable number of these patients will suffer from post-thrombotic syndrome (PTS) leading to impaired quality of life in more than 50%. Endovascular treatment for iliac vein obstruction using stents is known to alleviate PTS symptoms in selected patients. Purpose To report the Danish long-term results of endovascular treatment with iliac stenting. Material and Methods From 2000 to 2013 consecutive patients were evaluated and 19 patients with severe venous claudication were identified and subsequently underwent angioplasty and stenting. AC treatment was prescribed for 6 months, and knee-high class II compression stocking recommended for 1 year. Scheduled follow-up was done in the outpatient clinic at 6 weeks, 3 months, and annually thereafter. Results Nineteen patients, all women, all with left-sided iliac vein obstruction, and all with severe PTS symptoms were included. The median follow-up time was 81 months (range, 1–146 months; mean, 69 months). Primary patency rate of the inserted iliac stent was 89% (17/19) and 16 patients (84 %) had almost or total symptom relief at follow-up. Conclusion Endovascular stenting of iliac obstruction in local anesthesia is minimally invasive and shows excellent long-term outcomes for patients suffering from PTS. PMID:26445677

    Introduction This study aimed to evaluate the short and long-term results of endoscopic dacryocystorhinostomy (DCR) with and without silicone stenting in chronic dacrocystorhinitis due to postsaccal blockage. Methods The study involved a case series of consecutive 89 patients (128 eyes) who underwent endoscopic DCR. All patients were operated on by the senior author. The stent group comprised 63 eyes (44 patients), for which the DCR was performed between September 2002 and September 2005. The non-stent group with 65 eyes (45 patients) underwent the DCR between October 2005 and December 2006. The follow-up duration was up to 33 months after surgery. The statistical significance (p-value) was calculated using the chi-squared test. Results The short-term success rate at six months’ follow-up was 70% in the stent group and 97% in the non-stent group (p=0.0005) while the long-term success rate at 33 months was only 57% in stent group compared with 89% in the non-stent group (p=0.0003). Conclusions In this study, the non-stent group showed a higher success rate than the stent group on both short and longterm follow-up. Our study suggests that postoperative stents are not necessary for primary DCR and may be associated with a worse outcome. PMID:23827291

    Luminal breast cancer constitutes a group of highly heterogeneous diseases with a sustained high risk of late recurrence. We aimed to develop comprehensive and practical nomograms to better estimate the long-term survival of luminal breast cancer.Patients with luminal breast cancer diagnosed between 1990 and 2006 were retrieved from the Surveillance, Epidemiology, and End Results (SEER) database and randomly divided into the training (n = 87,867) and validation (n = 88,215) cohorts. The cumulative incidence function (CIF) and a competing-risks model were used to estimate the probability of breast cancer-specific survival (BCSS) and death from other causes. We integrated significant prognostic factors to build nomograms and subjected the nomograms to bootstrap internal validation and to external validation.We screened 176,082 luminal breast cancer cases. The 5- and 10-year probabilities of overall death were 0.089 and 0.202, respectively. The 5- and 10-year probabilities of breast cancer-specific mortality (BCSM) were 0.053 and 0.112, respectively. Nine independent prognostic factors for both OS and BCSS were integrated to construct the nomograms. The calibration curves for the probabilities of 5- and 10-year OS and BCSS showed excellent agreement between the nomogram prediction and actual observation. The C-indexes of the nomograms were high in both internal validation (0.732 for OS and 0.800 for BCSS) and external validation (0.731 for OS and 0.794 for BCSS).We established nomograms that accurately predict OS and BCSS for patients with luminal breast cancer. The nomograms can identify patients with higher risk of late overall mortality and BCSM, helping physicians in facilitating individualized treatment. PMID:26967253

    Lung cancer is the leading cause of cancer death in women, accompanied by greater psychological distress than other cancers. There is minimal but increasing awareness of the impact of lung cancer stigma (LCS) on patient outcomes. LCS is associated with increased symptom burden and decreased quality of life. The purpose of this study was to explore the experience of female long-term lung cancer survivors in the context of LCS and examine how participants discursively adhere to or reject stigmatizing beliefs. Findings situated within Cataldo and colleagues' theoretical model include: (1) addiction and tobacco marketing as possible precursors for LCS, (2) the possible role of expert providers as LCS enhancers, (3) response of overlapping complicated identity shifts, (4) simultaneous rejection and assumption of LCS, and (5) information control via advocacy activities as a LCS mitigation response. These findings expand the current understanding of LCS, and call for future conceptual exploration and theoretical revision, particularly with respect to the possibility of interaction between relevant/related stigma(s) and LCS. As the number of women living with lung cancer increases, with longer survival times, the effect of LCS and other experiences of discrimination on patient outcomes could be substantial.

    Objective. To determine the long-term stricture-free rate after visual internal urethrotomy following initial and follow-up urethrotomies. Methods. The records of all male patients who underwent direct visual internal urethrotomy for urethral stricture disease in our hospital between July 2004 and May 2012 were reviewed. The Kaplan-Meier method was used to analyze stricture-free probability after the first, second, third, fourth, and fifth urethrotomies. Results. A total of 301 patients were included. The overall stricture-free rate at the 36-month follow-up was 8.3% with a median time to recurrence of 10 months (95% CI of 9.5 to 10.5, range: 2–36). The stricture-free rate after one urethrotomy was 12.1% with a median time to recurrence of eight months (95% CI of 7.1–8.9). After the second urethrotomy, the stricture-free rate was 7.9% with a median time to recurrence of 10 months (95% CI of 9.3 to 10.6). After the third to fifth procedures, the stricture-free rate was 0%. There was no significant difference in the stricture-free rate between single and multiple procedures. Conclusion. The long-term stricture-free rate of visual internal urethrotomy is modest even after a single procedure. PMID:26494995

    Objective To analyze the management of pediatric trauma and the efficacy of the Pediatric Trauma Score (PTS) in classifying injury severity and predicting prognosis. Design A retrospective case series. Setting The Children’s Hospital of Eastern Ontario, a major pediatric trauma centre. Patients One hundred and forty-nine traumatized children with 2 or more injuries to 1 body system or a single injury to 2 or more body systems. Interventions Use of the PTS and Glasgow Coma Scale score in trauma management. Main outcome measures Types of injuries sustained, complications, missed injuries, psychosocial effects and residual deficiencies. Results The average PTS was 8.5 (range from −3 to 11). The total number of injuries sustained was 494, most commonly closed head injury (86). Forty-two percent of children with an average trauma score of 8.5 were treated surgically. There were 13 missed injuries, and complications were encountered in 57 children, the most common being secondary to fractures. Forty-eight (32%) children had residual long-term deficiency, most commonly neurologic deficiency secondary to head injury. Conclusions Fractures should be stabilized early to decrease long-term complications. A deficiency of the PTS is the weighting of open fractures of a minor bone. For example, metacarpal fracture is given the same weight as an open fracture of the femur. Neuropsychologic difficulties secondary to trauma are a major sequela of trauma in children. PMID:11939656

    Uncemented, threaded acetabular components with smooth surface treatment were widely used in continental Europe in the 1970s and 1980s for primary total hip arthroplasty (THA). Previously published studies showed high failure rates in the mid-term. In a consecutive series of 116 patients, 127 threaded cups with smooth surface treatment (Weill cup; Zimmer, Winterthur, Switzerland) were implanted in combination with one type of uncemented stem. Patients were followed up clinically and radiographically. Mean time of follow-up was 17 years (range 15–20). At the time of follow-up, the acetabular component had been revised or was awaiting revision in 30 hips (24%). Two hips were revised for infection and 23 for aseptic loosening. Four polyethylene liners were exchanged because of excessive wear. One hip was awaiting revision. The survival rate for all acetabular revisions including one hip awaiting revision was 75% (95%CI: 65–85%) at 17 years. These results support the view that smooth, threaded acetabular components do not provide satisfactory long-term fixation and should be abandoned. It is important to closely monitor patients with these components as the failure rate remains high in the long-term. PMID:19629480

    Controversy persists over the use of the flexor carpi ulnaris for transfer to the extensor digitorum communis in the treatment of radial nerve palsy. Six patients with complete, irreparable radial nerve palsies were treated in part with the flexor carpi ulnaris to extensor digitorum communis tendon transfer (standard transfers: pronator teres to extensor carpi radialis brevis, flexor carpi ulnaris to extensor digitorum communis, and palmaris longus to the rerouted extensor pollicis longus) and were functionally tested for long-term results. The average follow-up time was 8 years (range, 3-15). A control group was comprised of 10 volunteers of similar demographics. This study evaluates the long-term functional recovery in three categories: range of motion, dynamic power of wrist motion, and functional ability as determined by work simulation techniques. The activities simulated were swinging a hammer, sawing wood, tightening screws, and using pliers. A functional range of motion was maintained in all patients, and the power of wrist motion was sufficient to perform all activities of daily living. The work simulation testing revealed no significant difference between the tendon transfer patients and control group with respect to hand dominance and normal variance. All patients were able to perform the simulated work with the same variance in power as the control group. Despite the obvious anatomic loss, wrist function is not significantly impaired after flexor carpi ulnaris tendon transfer for radial nerve palsy. PMID:8522738

    Objectives. We explored long-term health consequences of age at sexual initiation and of abstinence until marriage to evaluate empirical support for the claim that postponing sexual initiation has beneficial health effects. Methods. We analyzed data from the 1996 National Sexual Health Survey, a cross-sectional study of the US adult population. We compared sexual health outcomes among individuals who had initiated sexual activity at an early or late age versus a normative age. We also compared individuals whose first sexual intercourse had occurred before versus after marriage. Results. Early initiation of sexual intercourse was associated with various sexual risk factors, including increased numbers of sexual partners and recent sexual intercourse under the influence of alcohol, whereas late initiation was associated with fewer risk factors. However, both early and late initiation were associated with sexual problems such as problems with arousal and orgasm, primarily among men. Relationship solidity and sexual relationship satisfaction were not associated with early or late initiation. Conclusions. Early sexual debut is associated with certain long-term negative sexual health outcomes, including increased sexual risk behaviors and problems in sexual functioning. Late initiation was also associated with sexual problems, especially among men. Further research is needed to understand how sexual initiation patterns affect later health outcomes. PMID:18048793

    The analysis of immediate and long-term results of the surgical treatment of 286 patients, operated for traumatic mandibular fractures in the Department of Oral and Maxillofacial Surgery, National O. O. Bogomolets Medical University. In 67% of patients the anatomical shape of the bone was adequately restored. The presence of residual displacements in other cases was determined by the fracture type and localization, the technical complexity of the surgical intervention, lack of fixation rigidity under certain functional load conditions. In long terms of observation the infection and inflammatory complications were observed in 13.4% of patients, delayed unition and non-unition of bone fragments occurred--in 4.7%, arthosis with persistent dysfunction of the temporomandibular joint--in 6.7%, fibrous ankylosis--in 1.3%. Secondary displacement of fragments was observed in 23.5% of patients due to insufficient stiffness and reliaability of the bone-fixatorsystem. The non-precise reposition of fragments and secondary displacements in the early and late postoperative period were the main cause of occlusal disturbances of various severities, noted in 28% of operated patients, limitation of mouth opening (10%), TMJ disorders and changes in masticatory stereotype (33%), the sensation of pain and discomfort in tough food chewing (35%). A statistical analysis of the effectiveness of different osteosynthesis methods depending on the type and localization of the fracture was carried out and recommendations for usage of fixation devices in clinical practice were given.

    Lipopolysaccharide (LPS), a major proinflammatory glycolipid component of the gram-negative bacterial cell wall, is one of the agents ubiquitously present as contaminant on airborne particles, including air pollution, organic dusts, and cigarette smoke. Chronic exposure to significant levels of LPS is reported to be associated with the development and/or progression of many types of lung diseases, including asthma, chronic bronchitis, and progressive irreversible airflow obstruction, that are all characterized by chronic inflammatory processes in the lung. In the present study, pathologic effects of long-term LPS exposure to the lung were investigated in detail. To this end, a murine model in which mice were exposed to repeated intratracheal instillation of Escherichia coli LPS was developed. We show that long-term LPS instillation in mice results in persistent chronic pulmonary inflammation, characterized by peribronchial and perivascular lymphocytic aggregates (CD4(+), CD8(+), and CD19(+)), parenchymal accumulation of macrophages and CD8(+) T cells, and altered cytokine expression. Furthermore, airway and alveolar alterations such as mucus cell metaplasia, airway wall thickening, and irreversible alveolar enlargement accompanied the chronic inflammatory response. Interestingly, the observed inflammatory and pathologic changes mimic changes observed in human subjects with chronic inflammatory lung diseases, especially chronic obstructive pulmonary disease (COPD), suggesting that this murine model could be applicable to dissect the role of inflammation in the pathogenesis of these disease conditions.

    Purpose: To determine whether high-dose radiation leads to improved outcomes in patients with non-small-cell lung cancer (NSCLC). Methods and Materials: This analysis included 106 patients with newly diagnosed or recurrent Stages I-III NSCLC, treated with 63-103 Gy in 2.1-Gy fractions, using three-dimensional conformal radiation therapy (3D-CRT) per a dose escalation trial. Targets included the primary tumor and any lymph nodes {>=}1 cm, without intentionally including negative nodal regions. Nineteen percent of patients (20/106) received neoadjuvant chemotherapy. Patient, tumor, and treatment factors were evaluated for association with outcomes. Estimated median follow-up was 8.5 years. Results: Median survival was 19 months, and 5-year overall survival (OS) was 13%. Multivariate analysis revealed weight loss (p = 0.011) and radiation dose (p = 0.0006) were significant predictors for OS. The 5-year OS was 4%, 22%, and 28% for patients receiving 63-69, 74-84, and 92-103 Gy, respectively. Although presence of nodal disease was negatively associated with locoregional control under univariate analysis, radiation dose was the only significant predictor when multiple variables were included (p = 0.015). The 5-year control rate was 12%, 35%, and 49% for 63-69, 74-84, and 92-103 Gy, respectively. Conclusions: Higher dose radiation is associated with improved outcomes in patients with NSCLC treated in the range of 63-103 Gy.

    Background Successful treatment options for cancer result in more young long-term survivors prone for long-term complications. Carotid artery vasculopathy is a potential long-term complication after radiotherapy of the neck, resulting in cerebrovascular events and probably deficits in cognitive and motor functioning. Better insight into the underlying pathofysiology of radiotherapy induced carotid artery vasculopathy is needed for prognostic purposes and to develop preventive strategies. Methods/Design The current study is a prospective cohort study on the long-term cerebral and vascular complications after radiotherapy of the neck, in 103 patients treated for head and neck cancer, included in our study database between 2002 and 2008. Baseline protocol (before radiotherapy) included screening for cerebrovascular risk factors and intima media thickness measurement of carotid arteries by ultrasonography. Follow-up assessment more than 5 years after radiotherapy included screening of cerebrovascular risk factors, cerebrovascular events, neurological examination with gait and balance tests, extensive neuropsychological examination, self-report questionnaires, ultrasonography of the carotid arteries with measurement of intima media thickness and elastography, magnetic resonance imaging of the brain and magnetic resonance angiography of the carotid arteries. Discussion The current study adds to the understanding of the causes and consequences of long-term cerebral and vascular changes after radiotherapy of the neck. These data will be helpful to develop a protocol for diagnostic and preventive strategies for long-term neurological complications in future head and neck cancer patients with anticipated radiotherapy treatment.

    Forty-five patients (49 knees) who had torn complete or incomplete discoid lateral menisci were treated during the period from 1968 to 1980. Both instrumentation and specific techniques considerably evolved in the arthroscopic complete excision the torn discoid meniscus. The current technique involves the initial removal of the anterior portion of the meniscus, as this allows clearer visualization during the procedure, more space for manipulating surgical instruments, and a reduced operative time. Twenty-four knees (22 patients) were followed for a mean of four years three months. Of this group, 78% were rated excellent or good and 21% were rated fair. There were no poor results. The results in the group treated by total meniscectomy were better than those in the group treated with partial meniscectomy. Three patients were treated by peripheral meniscal repair under arthroscopic control, but the long-term results are not available. PMID:6896480

    The fundamental observation that the temporal spacing of learning episodes plays a critical role in the efficiency of memory encoding has had little effect on either research on long-term potentiation (LTP) or efforts to develop cognitive enhancers. Here we review recent findings describing a spaced trials phenomenon for LTP that appears to be related to recent evidence that plasticity thresholds differ between synapses in the adult hippocampus. Results of tests with one memory enhancing drug suggest that the compound potently facilitates LTP via effects on high threshold synapses and thus alters the temporally extended timing rules. Possible implications of these results for our understanding of LTP substrates, neurobiological contributors to the distributed practice effect, and the consequences of memory enhancement are discussed.

    Leaching studies on SRL-131 simulated defense waste glass have been carried out for a duration of two years. This glass contained nonradioactive elements and depleted uranium to simulate the waste content. The leachants used in this study were deionized water, a sodium bicarbonate/silicic acid solution (silicate water), a synthetic groundwater, and a high ionic strength K-Mg-Na-Cl brine. Two temperatures were used: 40/sup 0/C and 90/sup 0/C. The long-term results were in fair agreement with modeling calculations performed using the PHREEQE geochemical code. The leachability of SRL-131 glass from results up to two years followed the trend: deionized water > silicate water > synthetic groundwater > salt brine at 40/sup 0/C and deionized water approx. = synthetic groundwater > silicate water > salt brine at 90/sup 0/C. Solid state analyses are reported along with an Appendix containing a complete data set.

    Purpose To compare the long-term clinical outcomes of postmastectomy radiotherapy (PMRT) between breast cancer patients with and without immediate transverse rectus abdominis myocutaneous (TRAM) flap reconstruction. Methods The study included 492 patients with stage II or III breast cancer who underwent modified radical mastectomy (MRM) and chemotherapy followed by PMRT between 1997 and 2011. Cox regression model and Kaplan-Meier curves were calculated, and the log-rank test was used to evaluate the differences between overall and disease-free survival rates in the 2 groups. Results Among 492 patients, 213 patients had immediate TRAM flap reconstruction. The mean follow-up was 7.2 years (range, 11–191 months). The 5-year and 10-year disease free survival rates were 81% and 76% for the TRAM flap group and 78% and 73% for the non-flap group. The 5-year and 10-year overall survival rates were 89% and 73% for the TRAM flap group and 83% and 74% for the non-flap group. Conclusions There exists no statistically significant difference in the rates of local recurrence, distant metastasis, disease-free and overall survival when comparing immediate TRAM flap reconstruction with no reconstruction. Our results suggest that immediate TRAM flap reconstruction does not compromise long term clinical outcomes in breast cancer patients requiring PMRT. PMID:26863006

    Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) are used as standard therapies for advanced nonsmall cell lung cancer (NSCLC) patients with EGFR mutation positive. Because these targeted therapies could cause tumor necrosis and shrinkage, the purpose of the study is to search for a value of optimal tumor shrinkage as an appropriate indicator of outcome for advanced NSCLC.A total of 88 NSCLC enrollees of 3 clinical trials (IRESSA registration clinical trial, TRUST study and ZD6474 study), who received Gefitinib (250 mg, QD), Erlotinib (150 mg, QD), and ZD6474 (100 mg, QD), respectively, during December 2003 and October 2007, were retrospectively analyzed. The response evaluation criteria in solid tumors (RECIST) were used to identify responders, who had complete response (CR) or partial responses (PR) and nonresponders who had stable disease (SD) or progressive disease (PD). Receiver operating characteristics (ROC) analysis was used to find the optimal tumor shrinkage as an indicator for tumor therapeutic outcome. Univariate and multivariate Cox regression analyses were performed to compare the progression-free survival (PFS) and overall survival (OS) between responders and nonresponders stratified based on radiologic criteria.Among the 88 NSCLC patients, 26 were responders and 62 were nonresponders based on RECIST 1.0. ROC indicated that 8.32% tumor diameter shrinkage in the sum of the longest tumor diameter (SLD) was the cutoff point of tumor shrinkage outcomes, resulting in 46 responders (≤8.32%) and 42 nonresponders (≥8.32%). Univariate and multivariate Cox regression analyses indicated that (1) the responders (≤8.32%) and nonresponders (≥ -8.32%) were significantly different in median PFS (13.40 vs 1.17 months, P < 0.001) and OS (19.80 vs 7.90 months, P < 0.001) and (2) -8.32% in SLD could be used as the optimal threshold for PFS (hazard ratio [HR], 8.11, 95% CI, 3.75 to 17.51, P < 0.001) and OS (HR, 2.36, 95

METHODS A total of 25 patients with pilocytic astrocytomas underwent Gamma Knife surgery during the period 1992-2002. The median target volume was 2700 mm(3) (range 205-25,000 mm(3)). The 18 patients treated with 5 daily fractions received a median minimum target dose of 25 Gy. Doses for the 2 patients treated with 10 fractions over 5 days (2 fractions delivered on the same day at least 6 hours apart) were 23 and 28 Gy. For the 5 patients treated with a single fraction, the minimum target dose ranged from 13 to 20 Gy (median 16 Gy). RESULTS Complete regression occurred in 10 patients (40%) and partial regression in 10 patients (40%). The 10-year overall survival rate was 96% and the 10-year PFS rate was 80%. Target volume appeared to be a significant prognostic factor for PFS (p = 0.037). Temporary Grade 3 toxicity appeared in 2 patients (8%), and these patients were treated with corticosteroids for 2 months. Permanent Grade 4 toxicity appeared in 2 patients (8%) and was associated with neurocognitive dysfunction. In these 2 individuals, the neurocognitive dysfunction was also felt to be in part the result of the additional therapeutic interventions (4 in one case and 6 in the other) required to achieve durable control of their tumors. CONCLUSIONS Radiosurgery represents an alternative treatment modality for small residual or recurrent volumes of pilocytic astrocytomas and provides long-term local control. Target volume appears to be the most important factor affecting PFS. PMID:26991883

    Medulloblastoma is highly radioresponsive, and recent treatment results have improved greatly since the introduction of megavoltage machine in 1960s. There is increasing evidence for the potential cure of medulloblastoma if properly treated in its early stages. The curable group represents approximately 75% of diagnosed patients. Long-term treatment effects were examined in this study. The study reveals age-dependent late effects in learning ability; the patients less than 4-years-old at treatment had major learning problems; patients of 5 to 7 years old performed at satisfactory-to-low passing levels in school work; patients older than 8 years old had no major intellectual impairment. Short stature was common when growth potential was present at the time of therapy, but endocrine tests were generally negative. These observations indicate special educational requirement needs, especially for children treated at a young age.

    Subtotal parathyroidectomy was performed in a consecutive series of 292 patients with primary hyperparathyroidism. We evaluated the long-term postoperative results during a period of 16 years. Patients ranged in age from 14 to 83 years and included 176 women and 116 men. Of these, 16% had a history of exposure to radiation in childhood or adolescence, while thyroid disease requiring some form of thyroidectomy coexisted in 91 (31%) of the patients. Histologic information on three or more parathyroid glands was obtained in 73% of the cases. We considered 285 patients (97.6%) cured after their first operation. The remaining seven patients (2.4%) had persistent hyperparathyroidism. However, five were cured after a sternum-splitting mediastinal exploration and one after a second neck exploration. The seventh remains hypercalcemic despite a subsequent mediastinal exploration. Temporary postoperative hypoparathyroidism occurred in 10% of our cases and permanent hypoparathyroidism in 1%. There have been no instances of recurrent hyperparathyroidism.

    Primary renal lymphoma (PRL) is a rare disease of which the etiology and pathogenesis remain controversial, and there is currently no standard treatment for it. We present the results of a long-term followup of two patients who were diagnosed with PRL and treated with cyclophosphamide, adriamycin, vincristine, prednisolone and rituximab (CHOP + R) regimen. Both patients reached a complete response, and there is no evidence of recurrence after 4.5- and 5-year followup periods. Based on our experience and other recently published studies, we recommend the combination of CHOP + rituximab as the elective treatment for this disease. To our knowledge, this is the longest followup period with a complete response that has been reported with this modality of treatment. PMID:22997596

    Results of the analysis of the large, homogeneous set of measurements of Jupiter's emission at 16.7 and 22.2 MHz for the apparitions during the period 1966-1974 were presented. An update of the radio rotation period determination which includes provision for beaming effects due to variations in the Jovicentric declination of the earth was presented. Some estimates of the magnitude of possible long-term variations in the rotation period were also discussed. The data clearly shows the Io-independent emission features associated with the System III central meridian longitudes of all three major Io-related source regions. There is also some evidence for heretofore unrecognized Io-related emission features which are apparently independent of the central meridian longitude. The possibility of three kinds of emission are suggested: (1) Io-stimulated, sharply beamed emission, (2) Io-independent, sharply beamed emission, and (3) Io-stimulated, broadly beamed emission.

    We present long-term spectral and timing results from an INTEGRAL monitoring program of persistently bright neutron star Low-Mass X-ray Binaries, i.e. the three bright Atoll sources GX 3+1, GX 9+1 and GX 9+9, and the Z sources GX 5-1, GX 17+2, GX 340+0 and GX 349+2. From the available observing periods between 2003 and 2009, each lasting ~2 months, we have selected a few sample periods for each source, and analyzed all JEM-X and IBIS/ISGRI data with offsets <4 degrees. We seek an explanation for the dichotomy between the hard X-ray tails or lack thereof in the (otherwise very similar) X-ray spectra of Z sources and bright Atolls, respectively.

    Supplemental security income (SSI) and social security disability insurance (DI) are federal programs that provide disability benefits. We report on SSI/DI enrollment in a random sample of adult, long-term survivors of childhood cancer (n = 698) vs a comparison group without cancer (n = 210) from the Childhood Cancer Survivor Study who completed a health insurance survey. A total of 13.5% and 10.0% of survivors had ever been enrolled on SSI or DI, respectively, compared with 2.6% and 5.4% of the comparison group. Cranial radiation doses of 25 Gy or more were associated with a higher risk of current SSI (relative risk [RR] = 3.93, 95% confidence interval [CI] = 2.05 to 7.56) and DI (RR = 3.65, 95% CI = 1.65 to 8.06) enrollment. Survivors with severe/life-threatening conditions were more often enrolled on SSI (RR = 3.77, 95% CI = 2.04 to 6.96) and DI (RR = 2.73, 95% CI = 1.45 to 5.14) compared with those with mild/moderate or no health conditions. Further research is needed on disability-related financial challenges after childhood cancer. PMID:25770148

    The patient was a 57-year-old woman. In October 2011, she underwent distal gastrectomy, D2 lymphadenectomy, and Roux-en-Y reconstruction for gastric cancer (pT4a, pN3b, Stage ⅢC [JCGC 14th Edition]). She then received S-1 plus CDDP combination therapy and S-1 monotherapy as postoperative adjuvant chemotherapies for 1 year, and was followed up as an outpatient. In April 2013, a significant increase in the CA19-9 level was noted, and CT indicated a right ovarian tumor. Ovarian metastasis from the gastric cancer was diagnosed, and the response to 3 courses of weekly PTX was stable disease. No findings indicated metastasis to other organs. In July 2013, a salpingo-oophorectomy was performed, after which her CA19-9 level returned to the normal range. Follow-up was adopted as the postoperative strategy in part due to the desires of the patient. Presently, 3 years and 6 months after the initial surgery and 1 year and 9 months after the last surgery, no recurrence has been detected. Generally, ovarian metastasis from gastric cancer is considered to be associated with a poor prognosis. However, our patient showed long-term survival after surgeries for gastric cancer and asynchronous ovarian metastasis. Here, we report the details of our case and review the relevant literature.

    PD-1 immune checkpoint blockade occasionally results in durable clinical responses in advanced metastatic cancers. However, mechanism-based predictors of response to this immunotherapy remain incompletely characterized. We performed comprehensive genomic profiling on a tumor and germline sample from a patient with refractory lung adenocarcinoma who achieved marked long-term clinical benefit from anti-PD-L1 therapy. We discovered activating somatic and germline amino acid variants in JAK3 that promoted PD-L1 induction in lung cancer cells and in the tumor immune microenvironment. These findings suggest that genomic alterations that deregulate cytokine receptor signal transduction could contribute to PD-L1 activation and engagement of the PD-1 immune checkpoint in lung cancer.

    A comprehensive study was conducted to examine the performance and possible changes in the effectiveness of landfill surface covers. Three different profiles of mineral landfill caps were examined. The results of precipitation and flow measurements show distinct seasonal differences which are typical for middle-European climatic conditions. In the case of the simple landfill cap design consisting of a thick layer of loamy sand, approximately 100-200 L m(-2) of annual seepage into the landfill body occurs during winter season. The three-layer systems of the two other test fields performed much better. Most of the water which percolated through the top soil profile drained sideways in the drainage layer. Only 1-3% of precipitation percolated through the sealing layer. The long-term effectiveness of the mineral sealing layer depended on the ability of the top soil layer to protect it from critical loss of soil water/critical increase of suction. In dry summers there was even a loss in soil water content at the base of the 2.0 m thick soil cover. The results of this study demonstrate the importance of the long-term aspect when assessing the effectiveness of landfill covers: The hydraulic conductivity at the time of construction gives only an initial (minimum) value. The hydraulic conductivity of the compacted clay layer or of the geosynthetic clay liner may increase substantially, if there is no long-lasting protection against desiccation (by a thick soil cover or by a geomembrane). This has to be taken into account in landfill cover design. PMID:20937619

    Background On the range of diagnoses, course of treatment, and long-term outcome in patients who chose to receive homeopathic medical treatment very little is known. We investigated homeopathic practice in an industrialized country under everyday conditions. Methods In a prospective, multicentre cohort study with 103 primary care practices with additional specialisation in homeopathy in Germany and Switzerland, data from all patients (age >1 year) consulting the physician for the first time were observed. The main outcome measures were: Patient and physician assessments (numeric rating scales from 0 to 10) and quality of life at baseline, and after 3, 12, and 24 months. Results A total of 3,981 patients were studied including 2,851 adults (29% men, mean age 42.5 ± 13.1 years; 71% women, 39.9 ± 12.4 years) and 1,130 children (52% boys, 6.5 ± 3.9 years; 48% girls, 7.0 ± 4.3 years). Ninety-seven percent of all diagnoses were chronic with an average duration of 8.8 ± 8 years. The most frequent diagnoses were allergic rhinitis in men, headache in women, and atopic dermatitis in children. Disease severity decreased significantly (p < 0.001) between baseline and 24 months (adults from 6.2 ± 1.7 to 3.0 ± 2.2; children from 6.1 ± 1.8 to 2.2 ± 1.9). Physicians' assessments yielded similar results. For adults and young children, major improvements were observed for quality of life, whereas no changes were seen in adolescents. Younger age and more severe disease at baseline were factors predictive of better therapeutic success. Conclusion Disease severity and quality of life demonstrated marked and sustained improvements following homeopathic treatment period. Our findings indicate that homeopathic medical therapy may play a beneficial role in the long-term care of patients with chronic diseases. PMID:16266440

    Objective The objective of this study was to assess the long-term safety of linezolid in patients with chronic infections requiring treatment for ≥6 weeks. Enhanced monitoring for optic neuropathy was included to characterize the early development of this side effect and to identify ophthalmologic tests that might be valuable in early detection of this event. Methods This was a multicenter, open-label, pilot study of patients aged ≥18 years on long-term linezolid therapy. Matched control patients were included for baseline assessment comparison. Patients were assessed at study entry, monthly while on treatment, at the end of treatment, and 30 days following the last dose. Aggregate ocular safety data were reviewed. Response to treatment was reported. Results The study was terminated owing to slow enrollment. Twenty-four patients received linezolid; nine patients were included as matched controls. Linezolid was prescribed for a median of 80.5 days (range, 50–254 days). In patients with a reported clinical outcome, the majority were considered improved or cured. Common treatment-related adverse events (AEs) included anemia, peripheral neuropathy, polyneuropathy, vomiting, and asthenia, and were consistent with the known safety profile. Most AEs resolved or stabilized with discontinuation of treatment. Results of ophthalmologic tests in the one case adjudicated as probable linezolid-associated optic neuropathy revealed abnormal color vision, characteristic changes in the optic disk, and central scotomas in each eye. Conclusion In our small population, linezolid was generally well tolerated and AEs were consistent with the known safety profile. Extensive ophthalmologic testing of all 24 linezolid-treated patients identified one case adjudicated as probable, linezolid-associated optic neuropathy. PMID:27621644

    In order to obtain the deep arc structural image of Mariana, a large-scale seismic observation by using 58 long-term ocean bottom seismometers (LTOBS) had been performed from June 2003 until April 2004, which is a part of the MARGINS program funded by the NSF. Prior to this observation, a pilot long-term seismic array observation was conducted in the same area by using 10 LTOBSs from Oct. 2001 until Feb. 2003. By using seven LTOBS's data, those are about 11 months long, hypocenter determination was performed at first and more than 3000 local events were found, although the PDE list contains only 59. A 1D velocity structure based on the iasp91 model was used, and a systematic shift of epicenters between the PDE list and this study was seen. To investigate the detail of hypocenter distribution and the 3D velocity structure, the DD inversion (tomoDD: Zhang and Thurber, 2003) was applied for this data set with a 1D structure initial model except for the crust, which has been surveyed by using a dense airgun-OBS system (Takahashi et al., 2003). The result of relocated hypocenters shows double seismic zones until about 200km depth and a lined focuses along the current ridge axis in the back-arc basin, and the result of the tomographic inversion shows a image of subducting slab and a low-Vs region below the Pagan island erupted in 1981 at 80km depth. The mantle structure beneath the back-arc basin was not clearly resolved due to the inadequate source-receiver coverage, which is cleared in the recent experiment.

    AIM To evaluate the long term clinical results of mechanical no-alcohol-assisted laser epithelial keratomileusis (LASEK) versus standard photorefractive keratectomy (PRK) for low-moderate myopia. METHODS Twenty-five eyes treated with LASEK and twenty-five eyes treated with PRK were evaluated with a mean follow-up duration of 60mo. Mechanical separation of the epithelium was performed with blunt spatula and without application of alcohol. Laser ablation was performed with the MEL-70 excimer laser. All patients were examined daily until epithelial closure; at 1, 3, 6, and 12mo, and every year subsequently. Main outcome measures were uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), manifest refraction, haze, efficacy and safety indexes. RESULTS Twenty-one eyes and 22 eyes completed follow-up of 60mo in LASEK and PRK group respectively. Manifest refraction at 60mo follow-up was -0.01 and 0.26 in LASEK and PRK group respectively. In the LASEK group mean UDVA and mean CDVA after 60mo were 20/22 and 20/20 respectively (P>0.01). In the PRK group mean UDVA and mean CDVA at 60mo follow-up were 20/20 and 20/20 after 60mo (P>0.01). The efficacy indexes were 0.87 and 0.95, and the safety indexes were 1.25 and 1.4 respectively for LASEK group and PRK group. CONCLUSION Both standard PRK and no-alcohol LASEK offer safe and effective correction of low-moderate myopia in the long term without any statistically significant difference between the two groups.

    The TEXT and SOFT trials concluded that an aromatase inhibitor (AI) with ovarian ablation (OA) yields a higher 5-year disease-free survival than tamoxifen alone in premenopausal ER+ high-risk early breast cancer. However, the long-term health consequences and costs of OA, either by GnRH agonist or oophorectomy, have not been evaluated. The objective was to conduct a cost-effectiveness analysis comparing tamoxifen to OA with AI. Markov Monte Carlo simulation model estimated the costs and benefits of 3 endocrine strategies: (1) tamoxifen; (2) GnRH agonist with AI (GnRHa-AI); (3) bilateral salpingo-oophorectomy with AI (BSO-AI). Effectiveness was measured in life expectancy gain (years), and costs were averaged over a lifetime (USD 2015). Adverse events and deaths from each strategy were modeled in the United States population over a time horizon of 40 years. For women without prior chemotherapy (low-risk), tamoxifen alone was more effective (18.03 years) and less costly ($1566) than GnRHa-AI (17.66 years, $93,692) or BSO-AI (17.63 years, $25,892). For those with prior chemotherapy (high-risk), BSO-AI was more costly but more effective (16.78 years, $25,368) than tamoxifen alone (16.55 years, $1523) with an ICER of $102,290, while GnRHa-AI yielded an ICER of $443,376. The simulation estimated 787 and 577 deaths attributable to OA among 9320 high-risk women after BSO-AI and GnRHa-AI, respectively. There may be a role for ovarian ablation in premenopausal women with ER+ high-risk early breast cancer; however, this analysis raises concerns about the long-term health consequences of ovarian ablation and the potential effects on overall survival.

    Background: Smoking has been known to cause endothelial dysfunction and bronchial carcinoma and duration of smoking has been implicated in the effects of smoking on regular smokers. This study evaluated the effects of long-term smoking on some coagulation markers in chronic smokers. Materials and Methods: A total of 78 chronic smokers (age, 41 ± 20 years) where grouped according to duration of time they have smoked (2-6 years, 7-11 years, 12-16 years and 17-21 years), and included in the study. Bleeding time (BT), whole-blood clotting time (WBCT), total platelet count (TPC), prothrombin time (PT) and activated partial thromboplastin time with kaolin (APTTK) were estimated in the subjects using standard operative procedures. Statistical Analysis used: Graph pad prism software (Statmate) version 2.0 and SPSS version 20.0 were used for the statistical analysis and the test of significance was calculated using paired Student's t-test. Results: There was an inverse correlation between the durations of smoking and BT, WBCT, PT and APTTK coagulation markers and a linear correlation between the different durations and TPC, in the chronic smokers. The strongest effects was in the 12-16 years and 17-21 years duration (P < 0.05). Conclusion: The study revealed that long-term chronic cigarette-smoking can lead to haemostatic dysfunction in chronic smokers. Smoking should be generally discouraged as it could have far-reaching medical implications on this group of subjects, especially in bleeding emergency cases. PMID:24791044

    This presentation is about residents' reactions to sonic booms in a long-term sonic boom exposure environment. Although two phases of the data collection have been completed, the analysis of the data has only begun. The results are thus preliminary. The list of four authors reflects the complex multi-disciplinary character of any field study such as this one. Carey Moulton is responsible for Wyle Laboratories' acoustical data collection effort. Robert Baumgartner and Jeff Thomas of HBRS, a social science research firm, are responsible for social survey field work and data processing. The study is supported by the NASA Langley Research Center. The study has several objectives. The preliminary data addresses two of the primary objectives. The first objective is to describe the reactions to sonic booms of people who are living where sonic booms are a routine, recurring feature of the acoustical environment. The second objective is to compare these residents' reactions to the reactions of residents who hear conventional aircraft noise around airports. Here is an overview of the presentation. This study will first be placed in the context of previous community survey research on sonic booms. Next the noise measurement program will be briefly described and part of a social survey interview will be presented. Finally data will be presented on the residents' reactions and these reactions will be compared with reactions to conventional aircraft. Twelve community studies of residents' reactions to sonic booms were conducted in the United States and Europe in the 1960's and early 1970's. None of the 12 studies combined three essential ingredients that are found in the present study. Residents' long-term responses are related to a measured noise environment. Sonic booms are a permanent feature of the residential environment. The respondents' do not live on a military base. The present study is important because it provides the first dose/response relationship for sonic booms

    Purpose: Surgical resection is considered the desirable curative treatment for trigeminal schwannomas. However, complete resection without any complications remains challenging. During the last several decades, stereotactic radiosurgery (SRS) has emerged as a minimally invasive treatment modality. Information regarding long-term outcomes of SRS for patients harboring trigeminal schwannomas is limited because of the rarity of this tumor. The aim of this study was to evaluate long-term tumor control and functional outcomes in patients harboring trigeminal schwannomas treated with SRS, specifically with gamma knife surgery (GKS). Methods and Materials: Fifty-three patients harboring trigeminal schwannomas treated with GKS were evaluated. Of these, 2 patients (4%) had partial irradiation of the tumor, and 34 patients (64%) underwent GKS as the initial treatment. The median tumor volume was 6.0 cm{sup 3}. The median maximum and marginal doses were 28 Gy and 14 Gy, respectively. Results: The median follow-up period was 98 months. On the last follow-up image, 7 patients (13%) had tumor enlargement, including the 2 patients who had partial treatment. Excluding the 2 patients who had partial treatment, the actuarial 5- and 10-year progression-free survival (PFS) rates were 90% and 82%, respectively. Patients with tumors compressing the brainstem with deviation of the fourth ventricle had significantly lower PFS rates. If those patients with tumors compressing the brainstem with deviation of the fourth ventricle are excluded, the actuarial 5- and 10-year PFS rates increased to 95% and 90%, respectively. Ten percent of patients had worsened facial numbness or pain in spite of no tumor progression, indicating adverse radiation effect. Conclusions: GKS can be an acceptable alternative to surgical resection in patients with trigeminal schwannomas. However, large tumors that compress the brainstem with deviation of the fourth ventricle should be surgically removed first and then

    Stereotactic radiosurgery is an alternative to conventional surgery for the treatment of trigeminal neuralgia. To better define the safety of radiosurgery and optimal technical choices, we reviewed our patient records and the literature. A total of 334 patients presenting with trigeminal neuralgia were treated between December 1992 and September 2005. A minimum of 1 year of follow-up was available for 262 patients. The mean age was 68 years (range: 30-90); 128 patients were male and 134 female. A neurovascular conflict was clearly visualized on MRI in 167 patients. Twenty-one had a past history of multiple sclerosis and 110 had already received conventional surgical treatment for trigeminal neuralgia. The intervention consisted of gamma knife radiosurgery (GKS) to the retrogasserian cisternal portion of the Vth cranial nerve. The median maximal dose used was 85Gy (range: 70-90). Actuarial curves show a plateau at 5 years for both the risk of hypoesthesia and recurrence. At 5 years, 58% of the patients remain pain-free and 83% have no trigeminal nerve disturbance. The median delay for pain cessation was 15 days. The initial pain-relief rate was 89%. None of the complications reported for the other techniques were observed. Patient selection (typical versus atypical, age, past surgery, multiple sclerosis) and details of operative technique (maximum dose, volume of nerve treated, target location, etc.) had a major influence on the probability of pain relief and toxicity risk. The details of operative technique are turning out to have a major influence on the clinical results. In our experience, high-dose (80-90Gy) retrogasserian (7-8mm from the brainstem) GKS provides the patient with a better chance of long-term pain relief and a lower risk of trigeminal nerve functional disturbance. GKS applied to the cisternal anterior trigeminal nerve using high doses provided safe and effective treatment for trigeminal neuralgia over the long term. PMID:19339026

    Background Tennis elbow is a common condition that usually responds to conservative measures. In refractory cases, surgical intervention is indicated. A plethora of surgical techniques have been described. We report the mid- to long-term outcomes of the Boyd–McLeod procedure for refractory tennis elbow. Methods A retrospective analysis and current review of patients that had undergone the Boyd–McLeod procedure over a 12-year period was undertaken. Demographics, time to discharge, length of follow-up and outcome scores were collected. Results Seventy patients underwent surgery. Mean time to discharge was 15.35 weeks, with 88% successful outcomes. Fifty-four patients were available for current follow-up at mean of 5.52 years (range 1.17 years to 11.49 years). Range of motion in all patients was unchanged. There were no revision procedures. Mean (SD) Mayo Elbow Performance Score was 90.85 (13.11), with 75.5% returning a good or excellent score and 24.5% a fair outcome. The mean (SD) Oxford Elbow Score was 44.04 (6.92); mean (SD) pain score was 89.5 (17.58); mean (SD) function score was 95.34 (9.59) and mean (SD) socio-psychological score was 91.50 (17.01). Overall, 83% of patients had an Oxford Elbow Score of 43 or greater, suggesting excellent outcome. Conclusions We show that the Boyd–McLeod procedure is an excellent option over both the short- and long-term for refractory tennis elbow.

    Purpose: To review long-term outcomes following postoperative radiotherapy (RT) for extremity soft tissue sarcoma (STS) and identify variables affecting the therapeutic ratio. Methods and Materials: Between 1970 and 2008, 173 patients with localized extremity STS were treated with postoperative radiation. No patients received prior irradiation. Sixteen percent of tumors had recurred after initial surgery alone; 89% of tumors were high grade. The median patient age was 57 years (range, 18-86 years). Sixty-one percent underwent >1 surgery before RT in an attempt to achieve wide negative margins. Final margin status was negative in 70% and marginal or microscopically positive in 30%. The median time between final surgery and start of RT was 40 days. The median RT dose was 65 Gy (range, 49-74 Gy). The median follow-up for all patients was 10.4 years and 13.2 years among survivors. Results: At 10 years, local control (LC), cause-specific survival (CSS), and overall survival (OS) rates were 87%, 80%, and 70%, respectively, with 89% of local failures occurring within 3 years after treatment. On multivariate analysis, age >55 years (82% vs 93%, P<.05) and recurrent presentation (67% vs 91%, P<.05) were associated with inferior 10-year LC. The LC according to final margin status was 90% for wide negative margins vs 79% for marginal/microscopically positive margins (P=.08). Age >55 years and local recurrence were associated with inferior CSS and OS on multivariate analysis. Twelve percent of patients experienced grade 3+ toxicity; 12 of these occurred in patients with tumors of the proximal lower extremity, with the most common toxicity of pathologic fracture occurring in 6.3%. Conclusions: This large single-institution series confirms that postoperative RT for STS of the extremities provides good long-term disease control with acceptable toxicity. Our experience supports recurrent presentation and older age as adverse prognostic factors for LC.

    The treatment of acromegaly is based on surgery, drugs, and radiotherapy as a third-line option. Fractionated stereotactic radiotherapy (FSRT) is a new technique with a need for long-term evaluation. The purpose of the study was to evaluate long-term results of FSRT in acromegaly. Overall, 34 patients [sex ratio 1.12, age 45 (5-65) years] with a pituitary adenoma of 24.5 (9-76) mm including 20 invasive tumors were treated by radiotherapy in fractionated stereotactic conditions delivering 50 gy in 27 sessions. Baseline growth hormone (GH) and IGF1 levels were 18 (±14.5) and 632.6 (±339) µg/L, respectively. Indications of FSRT were failure of surgery and drug treatments (n = 30) or contraindication/refusal of surgery (n = 4). Hormonal control was defined by normal age- and sex-adjusted IGF1. Remission was defined by hormonal control after withdrawal of drugs for a minimum of three consecutive months. Data were analyzed in SPSS software with a significance level at p < 0.05. After a mean follow-up of 152 months, hormonal control was achieved in 33 patients (97 %) with withdrawal of drugs in 13 patients (38.2 %) without any recurrence. Factors found to be significantly associated to remission in a multivariate Cox regression were lower baseline hormone levels (GH and IGF1) and smaller tumor size. Tumor control was achieved in all patients. Acquired hypopituitarism after radiotherapy was the main side effect reported with a rate of 39 %. FSRT seems to be an effective and well tolerated third-line treatment of acromegaly, particularly adapted to macro adenomas treatment. PMID:25956280

    Here, we describe the case of a patient diagnosed with locally advanced breast cancer 8 years ago. Her treatment course was neoadjuvant chemotherapy, followed by mastectomy and then adjuvant radiotherapy and trastuzumab (TTZ). During the use of adjuvant targeted therapy, an incidental pregnancy was diagnosed. Four years later, she developed bone and cerebral metastases, and since then, she has received courses of TTZ, capecitabine, lapatinib, and radiotherapy with intermittent control of the disease. Her 7-year-old son presents a normal physical and long-term neurological developmental curve according to specialized evaluation. This case is unique for several reasons: the patient received the highest dose of TTZ yet described during pregnancy (4400 mg); there has been a long period of disease-free survival after treatment for locally advanced breast cancer and long overall survival despite successive disease progressions during the metastatic phase of the disease (97 months), and there was a monitored pediatric follow-up period (7 years).

    Background and Aim Because most colorectal cancer patients survive beyond five years, understanding quality of life among these long-term survivors is essential to providing comprehensive survivor care. We sought to identify personal characteristics associated with reported quality of life in colorectal cancer survivors, and sub-groups of survivors potentially vulnerable to very low quality of life. Methods We assessed quality of life using the Veterans RAND 12-item Health Survey within a population-based sample of 1,021 colorectal cancer survivors in the Seattle Colorectal Cancer Family Registry, approximately 5 years post-diagnosis. In this case-only study, mean physical component summary scores and mental component summary scores were examined with linear regression. To identify survivors with substantially reduced ability to complete daily tasks, logistic regression was used to estimate odds ratios for “very low” summary scores, defined as a score in the lowest decile of the reference US population. All cases were followed for vital status following QoL assessment, and mortality was analyzed with Cox proportional hazards regression. Results Lower mean physical component summary score was associated with older age, female sex, obesity, smoking, and diabetes or other co-morbidity; lower mean mental component summary score was associated with younger age and female sex. Higher odds of very low physical component summary score was associated with older age, obesity, less education, smoking, co-morbidities, and later stage at diagnosis; smoking was associated with higher odds of very low mental component summary score. A very low physical component score was associated with higher risk of mortality (hazard ratio (95% confidence interval): 3.97 (2.95–5.34)). Conclusions Our results suggest that identifiable sub-groups of survivors are vulnerable to very low physical components of quality of life, decrements that may represent meaningful impairment in completing

    Paediatric pelvic fractures are rare lesions. In the literature still controversy exists regarding the management of these injuries. The sequelae of these types of lesions has been described. We report the management and long term outcome of 8 patients with paediatric pelvic fractures treated in our institution. Associated injuries to the Risser's growth nuclei are described that has not been previously reported. Anatomical reduction of the displaced fracture should be considered to minimise the risk of long term functional impairment. PMID:20850743

    ABSTRACT Zebrafish are a major model for chemical genetics, and most studies use embryos when investigating small molecules that cause interesting phenotypes or that can rescue disease models. Limited studies have dosed adults with small molecules by means of water-borne exposure or injection techniques. Challenges in the form of drug delivery-related trauma and anesthesia-related toxicity have excluded the adult zebrafish from long-term drug efficacy studies. Here, we introduce a novel anesthetic combination of MS-222 and isoflurane to an oral gavage technique for a non-toxic, non-invasive and long-term drug administration platform. As a proof of principle, we established drug efficacy of the FDA-approved BRAFV600E inhibitor, Vemurafenib, in adult zebrafish harboring BRAFV600E melanoma tumors. In the model, adult casper zebrafish intraperitoneally transplanted with a zebrafish melanoma cell line (ZMEL1) and exposed to daily sub-lethal dosing at 100 mg/kg of Vemurafenib for 2 weeks via oral gavage resulted in an average 65% decrease in tumor burden and a 15% mortality rate. In contrast, Vemurafenib-resistant ZMEL1 cell lines, generated in culture from low-dose drug exposure for 4 months, did not respond to the oral gavage treatment regimen. Similarly, this drug treatment regimen can be applied for treatment of primary melanoma tumors in the zebrafish. Taken together, we developed an effective long-term drug treatment system that will allow the adult zebrafish to be used to identify more effective anti-melanoma combination therapies and opens up possibilities for treating adult models of other diseases.

    BACKGROUND We sought to identify differences among black and white Medicare-insured patients with colorectal cancer who underwent resection. METHODS Surveillance, Epidemiology and End Results–Medicare (SEER-Medicare) linked inpatient data from 1986 to 2005 were examined. Differences in short- and long-term outcomes among black vs white patients were investigated. RESULTS There were 125,676 (92.4%) white and 9,891 (7.6%) black patients who met the criteria. Black patients were younger (75.5 vs 77.2 years; P < .001) but had more comorbidities than did white patients (mean Charlson comorbidity index score 3.99 vs 3.87; P < .001). Black patients demonstrated greater odds of in-hospital mortality (odds ratio [OR], 1.43; 95% confidence interval [CI], 1.30 to 1.56) and readmission within 30 days (OR, 1.26; 95% CI, 1.18 to 1.34). Comparing 1986 to 1990 vs 2001 to 2005, black patients had greater odds of 30-day readmission (OR, 1.12 vs 1.31) but reduced odds of index in-hospital mortality (OR, 1.84 vs 1.28). Black patients had worse long-term survival after colorectal surgery (hazard ratio [HR], 1.21; 95% CI, 1.17 to 1.25; P < .001). CONCLUSIONS Black patients with colorectal cancer demonstrated increased risk of mortality and readmission after controlling for age, sex, and comorbidities. Although black vs white differences in perioperative mortality decreased over time, disparities in readmission and long-term survival persisted. PMID:23375764

    Purpose: To compare the early andlong-term outcomes of subclavian artery angioplasty in patients with aortoarteritis and atherosclerosis. Methods: Sixty-one subclavian artery angioplasties were performed in 55 consecutive patients with aortoarteritis (n= 32) and atherosclerosis (n= 23) between 1986 and 1995. An arch aortogram followed by a selective subclavian artery angiogram was done to profile the site and extent of the lesion, its relation to the vertebral artery, and the distal circulation. Percutaneous transluminal angioplasty (PTA) was performed via the femoral route for 56 stenotic lesions and 5 total occlusions. Results: PTA was successful in 52 (92.8%) stenotic lesions and 3 (60%) total occlusions. Three patients (5.4%) had complications, that could be effectively managed nonsurgically. Compared with atherosclerosis, patients with aortoarteritis were younger (27.4 {+-} 9.3 years vs 54.5 {+-} 10.5 years; p < 0.001), more often female (75% vs 17.4%; p < 0.001), gangrene was uncommon (0% vs 17.4%; p < 0.05), and diffuse involvement was seen more often (43.8% vs 4.4%; p < 0.001). The luminal diameter stenoses were similar before PTA (88.6 {+-} 9.7% vs 89.0 {+-} 9.1%; p= NS). Higher balloon inflation pressure was required to dilate the lesions of aortoarteritis (9.9 {+-} 4.6 ATM vs 5.5 {+-} 1.0 ATM; p < 0.001). This group had more residual stenosis (15.5 {+-} 12.4% vs 8.3 {+-} 9.4%; p < 0.05) after PTA. There were no neurological sequelae, even in PTA of prevertebral lesions. On 3-120 months (mean 43.3 {+-} 28.9 months) follow-up of 40 patients, restenosis was more often observed in patients with aortoarteritis, particularly in those with diffuse arterial narrowing. These lesions could be effectively redilated. Clinical symptoms showed marked improvement after successful angioplasty. Conclusion: Subclavian PTA is safe and can be performed as effectively in aortoarteritis as in atherosclerosis, with good long-term results. Long-term follow-up shows that it

    Surgery has long been established as a valid alternative for chronic Achilles tendinopathies that have failed conservative treatment. Endoscopic procedures have shown satisfactory preliminary results for managing such injuries. The aim of the present study was to evaluate the long-term clinical outcomes of endoscopic surgery in patients with chronic midportion Achilles tendinopathy. We evaluated 27 endoscopic procedures in 24 patients (mean age 45.5 ± 8.9 years; 12 males and 12 females) with chronic Achilles tendinopathy and at least 5 (mean 7.7, range 5 to 14) years of follow-up. All ambulatory procedures consisted of paratenon debridement and longitudinal tenotomies. The clinical evaluation included 2 specific functional rating systems (the Achilles Tendon Scoring System and the Victorian Institute Sport Assessment-Achilles questionnaire) and a pain visual analog scale. Patient satisfaction with the procedure was assessed using a patient global assessment response to therapy Likert scale score. All patients had an improved clinical outcome at the final follow-up visit. Both scoring systems showed significant improvement in all clinical outcomes at the last follow-up visit. The Victorian Institute Sport Assessment-Achilles questionnaire score had improved from 37.0 ± 4.9 points preoperatively to 97.5 ± 12.1 points postoperatively (p = .0006). The Achilles Tendon Scoring System score had improved from 32.6 ± 13.1 points preoperatively to 97.2 ± 12.3 points postoperatively (p = .000006). The pain visual analog scale score averaged 0.2 ± 1.1, and the patient global assessment response to therapy score was 0.25 ± 0.71. The percentage of patients with an excellent patient global assessment response to therapy score was 85.1%. Two postoperative problems were reported (7.4%): a delayed keloid lesion and a seroma with chronic fistula. The infection rate and systemic complication rate were 0%. In conclusion, endoscopic surgery provided a high rate of excellent

    To study the immediate and long-term results of balloon aortic valvuloplasty (BAV) in a large cohort of patients with rheumatic valvular aortic stenosis. Single tertiary care center retrospective data analysis of immediate and long-term outcomes in patients following BAV from 2000 to 2008. Ninety-two patients with rheumatic aortic stenosis (AS) were studied who underwent BAV. Mean age of patients was 21.7 years (95 % CI 14.3-28.9) with mean follow-up period of 5.7 years (±SD 1.3). Intervention resulted in successful BAV (more than 50 % reduction in baseline gradient) in 79 (85.9 %) subjects (Group A) and partially successful BPV (<50 % reduction in baseline gradient) in 8 (8.7 %) subjects (Group B). BAV failed in 5 (5.4 %) subjects (Group C). Concomitant balloon mitral valvuloplasty was done in 23/92 cases. Mean left ventricular systolic pressure decreased from 165.6 (95 % CI 142.7-196.3) to 110.9 mmHg (95 % CI 92.1-129.6), (P < 0.001) and mean aortic valve (AV) gradient from 50.7 (95 % CI 35.12-66.22) to 27.2 mmHg (95 % CI 25.83-31.23), (P < 0.001). The mean change in ejection fraction and mean AV gradient were significantly different between success (Groups A and B) and failure groups (P < 0.001). Different grades of aortic regurgitation were noted in 32 (34.78 %) patients post BAV (severe regurgitation in 2.18 %). Anova post hoc analysis showed sustained gradient reductions at 1- and 5-year follow-up (P > 0.05). The need for surgery was much lower in Group A (2.5 %) compared to Group B (50 %) and C (100 %). BAV is an effective treatment strategy in dominant AS in multi valvular rheumatic disease situations. Combined aortic and mitral valvuloplasty was performed in one-fourth of study patients.

    Aims The long term results of the Legeais BioKpro III keratoprosthesis are presented for seven patients with severe corneal scarring. Methods The study took place at Moorfields Eye Hospital, London. Patients had either end stage ocular surface disease or corneal opacification after multiple failed graft surgery, with the potential for significant visual improvement. After insertion the device was covered with a conjunctival flap or buccal mucous membrane graft, which was later opened to expose the optic. The outcome measures were vision, complications, and retention of the device. Results The BioKpro III was inserted into seven patients with severe corneal scarring: ocular cicatricial pemphigoid, measles keratitis, thermal injury, Stevens‐Johnson syndrome, aniridia, chemical injury, and congenital rubella. The follow up was 18–48 months. The keratoprosthesis failed in six, because of extrusion occurring 2–28 months postoperatively. Retroprosthetic membranes occurred in three patients, and endophthalmitis in one. Vision improved from hand movements to 6/12 in the only patient who retained the KPro; however he was troubled by mucus accumulation on the optic. Conclusions The one success has been in a patient with thermal burns. The remaining results have been poor, with the KPro extruding in six of the seven patients. PMID:16929061

    The carcinogenicity of benzodiazepines (BZDs) is still unclear. We aimed to assess whether long-term benzodiazepines use is risk for cancer.We conducted a longitudinal population-based case-control study by using 12 years from Taiwan National Health Insurance database and investigated the association between BZDs use and cancer risk of people aged over 20 years. During the study period, 42,500 cases diagnosed with cancer were identified and analyzed for BZDs use. For each case, six eligible controls matched for age, sex, and the index date (ie, free of any cancer in the date of case diagnosis) by using propensity score. For appropriate risk estimation, we observed the outcomes according to their length of exposure (LOE) and defined daily dose (DDD). To mimic bias, we adjusted with potential confounding factors such as medications and comorbid diseases which could influence for cancer risk during the study period. The data was analyzed by using Cox proportional hazard regression and conditional logistic regression.The finding unveils benzodiazepines use into safe and unsafe groups for their carcinogenicity. The use of diazepam (HR, 0.96; 95%CI, 0.92-1.00), chlorodizepoxide (HR, 0.98; 95%CI, 0.92-1.04), medazepam (HR, 1.01; 95%CI, 0.84-1.21), nitrazepam (HR, 1.06; 95%CI, 0.98-1.14), oxazepam (HR, 1.05; 95%CI, 0.94-1.17) found safer among BZDs. However, clonazepam (HR, 1.15; 95%CI, 1.09-1.22) were associated with a higher risk for cancers. Moreover, specific cancer risk among BZDs use was observed significantly increased 98% for brain, 25% for colorectal, and 10% for lung, as compared with non-BZDs use.Diazepam, chlordiazepoxide, medazepam, nitrazepam, and oxazepam are safe among BZDs use for cancer risk. Our findings could help physicians to select safer BZDs and provide an evidence on the carcinogenic effect of benzodiazepines use by considering the LOE and DDD for further research. PMID:25674736

    A 71-year-old man with predialysis terminal renal insufficiency experienced peritoneal dissemination 1.5 years after low anterior resection for advanced rectal cancer. He received FOLFIRI therapy (70% dose); he achieved partial response (PR) under computed tomography and stable disease (SD) was maintained over a long term. Although Grade 3 myelosuppression was occasionally noted, he was treated with FOLFIRI for 2 years without other severe complications and without requiring the initiation of hemodialysis. After the initiation of hemodialysis, FOLFIRI treatment was continued for 1 year until progressive disease (PD). He received mFOLFOX6 as second-line therapy for 6 months, followed by LV-5-FU and a molecular targeting agent. These treatments prolonged his survival for 1 year and 8 months. FOLFIRI can be administered as an effective first-line therapy even for patients with predialysis terminal renal impairment without major renal damage. FOLFOX and molecular targeting agents should be made available and prolonged survival can be expected for advanced colorectal cancer patients with terminal renal disease after the initiation of hemodialysis.

    Long-term morbidity was evaluated in 357 patients with testicular cancer who were treated by infradiaphragmatic radiotherapy between 1970 and 1982. Myelopathy developed in four patients, radiation osteomyelitis in one, and radiation hepatitis in another after treatment. Posttreatment gastrointestinal symptoms were recorded in the medical records of 4% of patients but were mentioned by 41% of 199 who answered a questionnaire. The moderate gastrointestinal problems were recorded by 17% of the patients compared with 6% in a control group of healthy men. Postirradiation peptic ulcer occurred in 9%. A dose relationship existed, the risk of posttreatment gastrointestinal problems being less when the midplane dose was less than 40 Gy. Forty-one of 63 men who wished to do so fathered at least one child after their radiotherapy. The overall posttreatment quality of life was comparable to that of the control group. The authors conclude that the risk of major posttreatment morbidity is minimal for testicular cancer patients who undergo infradiaphragmatic radiotherapy after orchiectomy. Slight gastrointestinal symptoms are relatively common without major impact on quality of life. Gonadal toxicity is not a significant complication. Infradiaphragmatic radiotherapy is a safe, routine adjuvant treatment of seminoma in orchiectomized patients with Stage I seminoma. The midplane dose should not exceed 36 Gy in these patients.

    Background Non-small cell lung cancer (NSCLC) represents 85% of all lung cancers. It is estimated that 60% of patients with NSCLC at time of diagnosis have advanced disease. The aim of this study was to investigate clinical and demographic prognostic factors of long term survival in patients with unresectable NSCLC. Methods We retrospectively reviewed data of 1,156 patients with NSCLC stage IIIB or IV who survived more than 60 days from the time of diagnosis and treated from August 1987 until March 2013 in the Oncology Department of Pulmonary Clinic of the General Hospital Papanikolaou. Initially univariate analysis using the log-rank test was conducted and then multivariate analysis using the proportional hazards model of Cox. Also Kaplan Meier curves were used to describe the distribution of survival times of patients. The level of significance was set at 0.05. Results The mean age at diagnosis was 62 years. About 11.9% of patients were women and 88.1% were male. The majority of cases were adenocarcinomas (42.2%), followed squamous (33%) and finally the large cell (6%). Unlike men, most common histological type among women was adenocarcinoma rather than squamous (63% vs. 10.9%). In univariate analysis statistically significant factors in the progression free survival (PFS) and overall survival (OS) were: weight loss ≥5%, histological type, line 1 drugs, line 1 combination, line 1 cycles and radio lung. Specifically radio lung gives clear survival benefit in the PFS and OS in stage IIIB (P=0.002) and IV (P<0.001). On the other hand, the number of distant metastases in stage IV patients did not affect OS, neither PFS. In addition patients who received platinum and taxane had better PFS (P=0.001) and OS (P<0.001) than those who received platinum without taxane. Also the third drug administration proved futile, since survival (682.06±34.9) (P=0.023) and PFS (434.93±26.93) (P=0.012) of patients who received less than three drugs was significantly larger.

    Gut microbes are essential for the degradation of dietary oxalate, and this function may play a role in decreasing the incidence of kidney stones. However, many oxalate-degrading bacteria are susceptible to antibiotics and the use of oxalate-degrading probiotics has only led to an ephemeral reduction in urinary oxalate. The objective of the current study was to determine the efficacy of using whole-community microbial transplants from a wild mammalian herbivore, Neotoma albigula, to increase oxalate degradation over the long term in the laboratory rat, Rattus norvegicus. We quantified the change in total oxalate degradation in lab rats immediately after microbial transplants and at 2- and 9-month intervals following microbial transplants. Additionally, we tracked the fecal microbiota of the lab rats, with and without microbial transplants, using high-throughput Illumina sequencing of a hyper-variable region of the 16S rRNA gene. Microbial transplants resulted in a significant increase in oxalate degradation, an effect that persisted 9 months after the initial transplants. Functional persistence was corroborated by the transfer, and persistence of a group of bacteria previously correlated with oxalate consumption in N. albigula, including an anaerobic bacterium from the genus Oxalobacter known for its ability to use oxalate as a sole carbon source. The results of this study indicate that whole-community microbial transplants are an effective means for the persistent colonization of oxalate-degrading bacteria in the mammalian gut. PMID:27312892

    Background Radiofrequency ablation (RFA) has been used to treat hepatocellular carcinoma (HCC) and liver metastases for more than 10 years with promising early outcomes. Preliminary results comparing percutaneous and surgical approaches have shown no difference in short-term outcomes. In this study, the longer-term outcomes were presented. Methods Patients with liver malignancies treated by RFA were prospectively studied from 2003 to 2011. Post-ablation assessment by computed tomography (CT) scan and serum biochemistry was performed at regular intervals. Recurrence rates and long-term survival were analysed. Results A total of 233 patients with liver malignancies (75.5% HCC and 24.5% liver metastases) were analysed. Three RFA approaches were used (percutaneous 58.4%, laparoscopic 9.4% and open 32.2%). The median follow-up time was 29 months. Complete ablation was achieved in 83.7%, with no difference between the two approaches. More wound and chest complications were observed in the surgical group. Intra-hepatic recurrences were observed in 69.5%; extra-hepatic recurrences were detected in 22.3%, with no difference between the two groups. There was no statistical difference between the two approaches in overall 1-, 3- and 5-year survival. Conclusion An extended period of follow-up in patients with liver malignancies showed that RFA is an effective treatment. No difference was demonstrated between the percutaneous and surgical approach, in terms of recurrence and survival. PMID:23458320

    Mild traumatic brain injury (mTBI) is an increasing public health concern as repetitive injuries can exacerbate existing neuropathology and result in increased neurologic deficits. In contrast to other models of repeated mTBI (rmTBI), our study focused on long-term white-matter abnormalities after bilateral mTBIs induced 7 days apart. A controlled cortical impact (CCI) was used to induce an initial mTBI to the right cortex of Single and rmTBI Sprague Dawley rats, followed by a second injury to the left cortex of rmTBI animals. Shams received only a craniectomy. Ex vivo diffusion tensor imaging (DTI), transmission electron microscopy (TEM), and histology were performed on the anterior corpus callosum at 60 days after injury. The rmTBI animals showed a significant bilateral increase in radial diffusivity (myelin), while only modest changes in axial diffusivity (axonal) were seen between the groups. Further, the rmTBI group showed an increased g-ratio and axon caliber in addition to myelin sheath abnormalities using TEM. Our DTI results indicate ongoing myelin changes, while the TEM data show continuing axonal changes at 60 days after rmTBI. These data suggest that bilateral rmTBI induced 7 days apart leads to progressive alterations in white matter that are not observed after a single mTBI. PMID:24473478

    Purpose: To evaluate the long-term safety, effectiveness, and prognostic factors of fractionated postoperative {beta}-irradiation. Methods and Materials: Between 1993 and 2005, 623 patients with 737 pterygium lesions were treated with a strontium-90 eye applicator after surgical excision. The median follow-up period was 60 months (range, 6.7-139.5). Of the 737 lesions, 644 were primary and 93 were recurrences after surgical removal alone. Fractionated radiotherapy (RT) to a total dose of 35 Gy in five to seven fractions was used. Results: A total of 73 local pterygium recurrences (9.9%) were noted. Of the recurrent cases, 80% were noted within 3 years after treatment. The 5- and 10-year probability of local control was 90% and 88%, respectively. The multivariate analysis for all cases demonstrated that gender, age, total radiation dose, recurrent pterygia, and interval between surgery and RT affected the overall local control rate. Late toxicities that might have been associated with strontium-90 RT included scleromalacia (scleral thinning) in nine eyes, adhesion of the eyelids in eight, cataracts in six, and scleral ulcer in five eyes. Conclusion: Fractionated strontium-90 RT to a total dose of approximately 35 Gy in five to seven fractions results in a similar local control rate as higher doses in other series, with an acceptable complication rate.

    Diffuse coronary artery disease (CAD) is considered unfavorable for interventional procedures; however, the results of stenting of diffuse CAD have not been completely characterized. We performed stenting in 100 consecutive patients with diffuse CAD, defined as significant stenosis >20 mm (n = 59 patients), multiple significant stenoses in the same artery (n = 23 patients), or significant narrowing involving the whole length of the coronary artery (n = 18 patients). Angiographic success was achieved in 103 arteries (100%) and clinical success was obtained in all 100 patients. There were no deaths; no patient had stent closure, acute myocardial infarction, or required emergency coronary artery bypass surgery. All 100 patients had >6 months follow-up (mean 18 +/- 7 months, range 7 to 31); 77 (77%) remained asymptomatic, and 5 (5%) had acute myocardial infarction, of whom 2 died (2%). In-stent restenosis was observed in 12 patients (12%) and repeat angioplasty was performed in 10. Including those patients who underwent repeat angioplasty, 89 (89%) maintained clinical improvement and 95 (95%) were alive and free of bypass surgery during follow-up. Life-table analysis showed 86% freedom from death, myocardial infarction, and target lesion revascularization at 28 months. Thus, selected patients with diffuse CAD may be treated with satisfactory acute and long-term results by stent implantation. PMID:11090785

    BACKGROUND The objective of this study was to test cladribine (2-CDA) alone and in combination with rituximab in patients with mantle cell lymphoma (MCL). METHODS Patients with MCL were treated on 2 sequential trials. In Trial 95-80-53, patients received 2-CDA as initial therapy or at relapse. In Trial N0189, patients received combination 2-CDA and rituximab as initial therapy. In both trials, 2-CDA was administered at a dose of 5 mg/m2 intravenously on Days 1 through 5 every 4 weeks for 2 to 6 cycles, depending on response. In Trial N0189, rituximab 375 mg/m2 was administered on Day 1 of each cycle. RESULTS Results were reported for 80 patients. Twenty-six previously untreated patients and 25 patients who had recurrent disease with a median age of 68 years received single-agent 2-CDA. The overall response rate (ORR) was 81% with 42% complete responses (CRs) in the previously untreated group. The median progression-free survival (PFS) was 13.6 months (95% confidence interval [95% CI], 7.2–22.1 months), and 81% of patients remained alive at 2 years. The ORR was 46% with a 21% CR rate in the recurrent disease group. The median PFS was 5.4 months (95% CI, 4.6–13.1 months), and 36% of patients remained alive at 2 years. Twenty-nine eligible patients with a median age of 70 years received 2-CDA plus rituximab. The ORR was 66% (19 of 29 patient), and the CR rate was 52% (15 of 29 patients). The median duration of response for patients who achieved a CR had not been reached at the time of the current report, and only 3 of the patients who achieved a CR developed recurrent disease at a median follow-up of 21.5 months. CONCLUSIONS 2-CDA had substantial single-agent activity in both recurrent and untreated MCL, and the results indicated that it may be administered safely to elderly patients. The addition of rituximab to 2-CDA may increase the duration of response. PMID:18470909

    The purpose of this paper is to discuss the background to advanced surface modification technologies and to present a new technique, involving the formation of a titanium oxide ceramic coating, with relatively long-term results of its clinical utilization. Three general techniques are used to modify surfaces: the addition or removal of material and the change of material already present. Surface properties can also be changed without the addition or removal of material, through the laser or electron beam thermal treatment. The new technique outlined in this paper relates to the production of a corrosion-resistant 2000-2500 A thick, ceramic oxide layer with a coherent crystalline structure on the surface of titanium implants. The layer is grown electrochemically from the bulk of the metal and is modified by heat treatment. Such oxide ceramic-coated implants have a number of advantageous properties relative to implants covered with various other coatings: a higher external hardness, a greater force of adherence between the titanium and the oxide ceramic coating, a virtually perfect insulation between the organism and the metal (no possibility of metal allergy), etc. The coated implants were subjected to various physical, chemical, electronmicroscopic, etc. tests for a qualitative characterization. Finally, these implants (plates, screws for maxillofacial osteosynthesis and dental root implants) were applied in surgical practice for a period of 10 years. Tests and the experience acquired demonstrated the good properties of the titanium oxide ceramic-coated implants.

Several of the land owners were not available to allow access to their respective properties, which created the need for several sample collection trips. This report documents the analytical results of the Rulison monitoring event and includes the trip report and the data validation package (Appendix A). The groundwater and surface water monitoring were shipped to the GEL Group Inc. laboratories for analysis. All requested analyses were successfully completed. Samples were analyzed for gamma-emitting radionuclides by high- resolution gamma spectrometry. Tritium was analyzed using two methods, the conventional tritium method, which has a detection limit on the order of 400 picocuries per liter (pCi/L), and the enriched method (for selected samples), which has a detection limit on the order of 3 pCi/L.

    The U.S. Department of Energy (DOE) Office of Legacy Management conducted annual sampling at the Rio Blanco, Colorado, Site for the Long-Term Hydrologic Monitoring Program (LTHMP) on May 20–21, 2015. This report documents the analytical results of the Rio Blanco annual monitoring event, the trip report, and the data validation package. The groundwater and surface water monitoring samples were shipped to the GEL Group Inc. laboratories for conventional analysis of tritium and analysis of gamma-emitting radionuclides by high-resolution gamma spectrometry. A subset of water samples collected from wells near the Rio Blanco site was also sent to GEL Group Inc. for enriched tritium analysis. All requested analyses were successfully completed. Samples were collected from a total of four onsite wells, including two that are privately owned. Samples were also collected from two additional private wells at nearby locations and from nine surface water locations. Samples were analyzed for gamma-emitting radionuclides by high-resolution gamma spectrometry, and they were analyzed for tritium using the conventional method with a detection limit on the order of 400 picocuries per liter (pCi/L). Four locations (one well and three surface locations) were analyzed using the enriched tritium method, which has a detection limit on the order of 3 pCi/L. The enriched locations included the well at the Brennan Windmill and surface locations at CER-1, CER-4, and Fawn Creek 500 feet upstream.

    AIM: To assess the effectiveness of minimally invasive versus traditional open surgical approach in the treatment of Zenker diverticulum. METHODS: Between 1976 and 2006, 297 patients underwent transoral stapling (n = 181) or stapled diverticulectomy and cricopharyngeal myotomy (n = 116). Subjective and objective evaluations of the outcome of the two procedures were made at 1 and 6 mo after operation, and then every year. Long-term follow-up data were available for a subgroup of patients at a minimum of 5 and 10 years. RESULTS: The operative time and hospital stay were markedly reduced in patients undergoing the endosurgical approach. Overall, 92% of patients undergoing the endosurgical approach and 94% of those undergoing the open approach were symptom-free or were significantly improved after a median follow-up of 27 and 48 mo, respectively. At a minimum follow-up of 5 and 10 years, most patients were asymptomatic after both procedures, except for those individuals undergoing an endosurgical procedure for a small diverticulum (< 3 cm). CONCLUSION: Both operations relieve the outflow obstruction at the pharyngoesophageal junction, indicating that cricopharyngeal myotomy has an important therapeutic role in this disease independent of the resection of the pouch and of the surgical approach. Diverticula smaller than 3 cm represent a formal contraindication to the endosurgical approach because the common wall is too short to accommodate one cartridge of staples and to allow complete division of the sphincter.

    Alumina-on-alumina bearings in THR may, in theory, provide an effective answer to osteolysis in young patients with ON of the femoral head. The purpose of this retrospective study was to report the long-term results of a series of 52 consecutive alumina THAs (41 patients) done for ON. The mean age of the patients at surgery was 41 years (range, 22-79 years). Cemented femoral stems with a 32-mm alumina head were used. Plain alumina cups were used and were either cemented (39 hips) or press-fit (13 hips). No patients were lost to followup. Sixteen hips have been revised. Aseptic loosening of the socket was the main cause of failure. At an average 16-year followup (range, 11-23.65 years), 26 hips were rated excellent and one hip was rated good. No osteolysis was observed and wear was undetectable. If revision for aseptic loosening was the end point, the rate of survival was 88.5% at 10 years for the socket and 100% at 10 years for the stem. With the alumina-on-alumina hip replacement done for ON, absence of osteolysis can be expected for as many as 24 years after the operation. New methods of socket fixation now are being explored.

    The authors studied long-term results of low-speed (10 ml/min) irrigated radiofrequency catheter ablation (RFA) of the lower isthmus (LI) in patients with typical atrial flutter (AF). This treatment was based upon combined use of local and indirect criteria of the block of isthmus conduction. The influence of RFA LI on quality of life (QL), echocardiographic parameters and cardiac rhythm variability (CRV) was studied. Low-speed irrigated RFA LI, based upon combined use of local and indirect criteria for verification of complete bidirectional blockade in this area, is an effective and safe method of treatment of patients with different variants of clinical course of typical AF which makes it possible to significantly improve QL characteristics and central hemodynamic parameters, and normalize CVR parameters as well. Self-organization of chaos, which realizes according to RR interval time rows, in patients with typical AF after RFA LI may be considered an additional criterion of the effectiveness of this operative intervention and a prognostic sign that predicts maintenance of sinus rhythm in this category of patients.

    The purpose of this study was to investigate the long-term results of conservative treatment of bilateral condylar fractures and to study the influence of possible functional impairment on intensity of pain and associated disability. We studied 71 patients (mean (SD) age 33 (14) years) with conservatively treated bilateral condylar fractures. Traffic crashes (n=42, 59%) and falls (n=20, 28%) were the main cause of the fractures. Forty-one patients (58%) were re-examined after about 90 months (mean 86, range 3-193). Five of the 41 (12%) had developed malocclusion, but did not experience any pain in the temporomandibular joint according to the Research Diagnostic Criteria for Temporomandibular Disorders. There was a significant negative relation between the presence of pain and the duration of follow up (p=0.02). Increasing age was significantly related to reduction in the intensity of pain (p=0.03). Of the remaining 30 patients who were not followed up, 2 had had bilateral sagittal split osteotomy and 1 a Le Fort I osteotomy. One patient had had orthodontic correction for a malocclusion. Including the five malocclusion patients, at least 9 of the total of 71 (13%) developed a malocclusion after conservative treatment. Functional impairment had no influence on the intensity of pain or pain-related disability in the patients with malocclusion after conservatively treated bilateral condylar fractures. This report may therefore be of value in the debate about whether open or closed treatment is better for bilateral mandibular condylar fractures. PMID:23375048

    The aim of the study was to evaluate the long-term results after surgery for acquired cholesteatoma in children and to contribute to the search for predictors of recurrence. During a 15-year period, 114 children underwent surgery. The patients were re-evaluated with a median observation time of 5.8 years. At the last re-evaluation 85 per cent of the ears were dry with an intact drum. Recurrence of cholesteatoma developed in 27 ears. The cumulated total recurrence rate was 24 per cent using the incidence rate calculation, applying Kaplan-Meier survival analysis the corresponding recurrence was 33 per cent. Recurrent disease occurred significantly more frequently in children younger than eight years, with a negative pre-operative Valsalva, with ossicular resorption and with large cholesteatomas. In conclusion, young children with poor Eustachian tube function and a large cholesteatoma with erosion of the ossicular chain, are at special risk of recurrence and should be observed for several years after surgery.

    Neer type II (Edinburgh type 3B) fractures of the lateral clavicle are unstable fractures. The optimal management of these fractures remains controversial with many surgical techniques described in the literature. Our study reports the long-term results of a modified suture (1.5-mm polydioxanone cord) and sling technique for these fractures to avoid complications associated with current techniques in the literature. Over a 5-year period, 23 patients who were (12 males, 11 females; 14 left, 9 right) with a mean age of 42 years were treated with this technique. At last follow-up, the mean Oxford score was 45.1 (range 36-48); the mean SPADI score was 7.4 (range 0-32.3); and the mean Constant score was 91.5 (range 71-100). There were one non-union and no malunion. All patients in our series, except one, returned to their pre-injury activity level. This modified suture fixation technique is safe, technically simple to perform and cheap. It achieves excellent rates of fracture union without the complications associated with other fixation methods in the literature. PMID:26794324

    Aim and Objective: Weekly administration of cisplatin (cis-diamminedichloroplatinum [CDDP]) appears more feasible and substantially more popular than the 3 weekly schedules due to better compliance. Different concurrent cisplatin schedules have been attempted including a daily schedule. We did a comparison of two consecutive single arm studies, i.e., use of weekly cisplatin versus daily cisplatin when used with concurrently with a moderately accelerated radiotherapy (RT) schedule. Patients and Methods: Two prospective feasibility, safety and efficacy studies were carried out consecutively within the department. The weekly CDDP study was done from August 2003 to August 2005 and daily CDDP study was conducted from November 2005 to June 2007. Both studies included locally advanced stage III and IV squamous cell carcinoma of the head and neck region with RT dose of 70 Gy. Concurrent single-agent cisplatin was administered weekly (35 mg/m2) in the first and daily (6 mg/m2) in the second study. Results: Weekly cisplatin study had 68 and daily CDDP study had 52 patients. The median follow-up in the two studies was 93 and 63 months, respectively. Compliance in the two studies was comparable. Acute Grade III/IV mucositis and dysphagia were significantly higher in weekly cisplatin study. Late Grade II/III toxicities such as xerostomia, dysphagia, ototoxicity and nephrotoxicity were similar. The 5 years locoregional control was 18% and 25% and 5 years overall survival rate was 32% and 31% in weekly and daily cisplatin studies, respectively. Conclusions: Modest acceleration along with either weekly or daily cisplatin, whichever is possible in one's setup, is do-able, provided due attention is paid to patient selection and supportive care.

    The long-term urodynamics of laparoscopic radical cystectomy with orthotopic ileal neobladder for bladder cancer remain unclear in the clinical setting. The present prospective observational study was conducted between January 2010 and December 2012 to evaluate the 6-month and 12-month follow-up data of urodynamic changes of bladder cancer patients who were initially treated by laparoscopic radical cystectomy with orthotopic ileal neobladder. A total of 53 eligible patients were included, and all patients were followed up for at least 12 months, with a median time of 18 months. During the follow-up period, no patients reported difficulty urinating, and the daily frequency of urination and the urine output were gradually improved with time. Dynamic urodynamic examinations showed that the maximum flow rate (11.4±1.1 vs. 7.3±1.4 ml/sec; P<0.001), residual urine content (22.8±10.5 vs. 40.7±12.7 ml; P<0.001), maximum bladder capacity (373.8±62.2 vs. 229.7±56.3 ml; P<0.001) and maximum bladder pressure during filling (35.8±6.7 vs. 26.4±7.0 cm H2O; P<0.001) at 12 months were all improved significantly compared with that at 6 months after the initial surgical treatment. However, there were no significant differences in maximum bladder pressure during voiding (75.7±24.7 vs. 73.1±24.7 cm H2O; P=0.618) and bladder compliance (26.9±13 vs. 27.4±13.1 cm H2O; P=0.848) at 12 and 6 months after initial surgical treatment. In conclusion, the urodynamics of this orthotopic ileal neobladder gradually improve, and its long-term urine storage and voiding functions are acceptable. PMID:25120652

    curative gastrectomy with D2/D3 lymphadenectomy. Survival curves in the two different histotypes (intestinal and mixed/diffuse) were superimposed in the first three years of follow-up and diverged thereafter. Likewise, survival curves as a function of site (fundus vs body/antrum) started to diverge after the first year. On the contrary, survival curves differed among age classes from the very beginning, due to different post-operative mortality, which increased from 0.5% in patients aged 65-74 years to 9.9% in patients aged 75-91 years; this discrepancy later disappeared. Accordingly, the proportional hazards assumption of the Cox model was violated, as regards age, site and histology. To cope with this problem, multivariable survival analysis was performed by separately considering either the first two years of follow-up or subsequent years. Histology and site were significant predictors only after two years, while T and N, although significant both in the short-term and in the long-term, became less important in the second part of follow-up. Increasing age was associated with higher mortality in the first two years, but not thereafter. Splitting survival time when performing survival analysis allows to distinguish between short-term and long-term risk factors. Alternative statistical solutions could be to exclude post-operative mortality, to introduce in the model time-dependent covariates or to stratify on variables violating proportionality assumption.

    Twenty-five patients had Russe anterior corticocancellous bone-grafting between 1973 and 1984 for twenty-six symptomatic established non-unions of the scaphoid. The mean duration of follow-up was eleven years (range, seven to eighteen years). Twenty-one (81 per cent) of the twenty-six scaphoid bones united. We developed two rating scales to evaluate the results of the operation. One scale, based on objective findings, included the radiographic appearance of the wrist, the range of motion, and strength; the other scale, based on subjective findings, comprised function, pain, perception of a decrease in performance because of limitation of motion or strength, and satisfaction. These scales were used to compare the objective and subjective results in patients who had a malunion of the scaphoid in which the lateral intrascaphoid angle was more than 45 degrees convex dorsally between the proximal and distal poles (a so-called flexion or humpback deformity, which results in extension of the proximal fragment of the scaphoid at the radiocarpal joint) with the results in patients who had no such deformity. The lateral intrascaphoid angle was more than 45 degrees in thirteen (50 per cent) of the twenty-six wrists. Although the difference in the objective results between the wrists that had a malunion and those that did not have a malunion was highly significant (p = 0.001), there was no significant difference in the subjective results between the two groups, including satisfaction of the patient (p = 0.39). Twenty-three patients (92 per cent) returned to full-time employment and twenty-two (88 per cent), to sports activities. Twenty-three patients (92 per cent) reported that they had pronounced relief of pain and that the procedure had improved their quality of life. The presence of this deformity of the scaphoid after bone-grafting for a symptomatic non-union was not predictive of a poor long-term subjective outcome. PMID:1400550

    AIM: To investigate the long-term oncologic outcomes and prognostic factors in patients with obstructive colorectal cancer (CRC) at multiple Japanese institutions. METHODS: We identified 362 patients diagnosed with obstructive colorectal cancer from January 1, 2002 to December 31, 2012 in Yokohama Clinical Oncology Group’s department of gastroenterological surgery. Among them, 234 patients with stage II/III disease who had undergone surgical resection of their primary lesions were analyzed, retrospectively. We report the long-term outcomes, the risk factors for recurrence, and the prognostic factors. RESULTS: The five-year disease free survival and cancer-specific survival were 50.6% and 80.3%, respectively. A multivariate analysis showed the ASA-PS (HR = 2.23, P = 0.026), serum Albumin ≤ 4.0 g/dL (HR = 2.96, P = 0.007), T4 tumor (HR = 2.73, P = 0.002) and R1 resection (HR = 6.56, P = 0.02) to be independent risk factors for recurrence. Furthermore, poorly differentiated cancers (HR = 6.28, P = 0.009), a T4 tumor (HR = 3.46, P = 0.011) and R1 resection (HR = 6.16, P = 0.006) were independent prognostic factors in patients with obstructive CRC. CONCLUSION: The outcomes of patients with obstructive CRC was poor. T4 tumor and R1 resection were found to be independent prognostic factors for both recurrence and survival in patients with obstructive CRC. PMID:27298566

    We aimed at comparing our long-term results after biliopancreatic diversion (BPD) with or without gastric preservation for morbid obesity. Between 1999 and 2009, we performed 540 BPD: 287 patients (group A) underwent BPD with distal gastric resection (BPD-AHS) and 253 (group B) underwent BPD associated with transitory vertical gastroplasty (TGR) with duodenal switch (DS). The results have been analyzed in terms of weight loss, improvement of comorbidities, and quality of life (Bariatric Analysis and Reporting Outcome System). The mean follow-up was 7.4 ± 2.9 years. One year after surgery, mean initial excess weight loss percentage was 69% for patients in group A (n = 287) and 65% for group B (n = 253); after 2-5 years, it was 74% for patients who underwent BPD-AHS (n = 130) and 75% for patients who underwent BPD-TGR-DS (n = 116); it was 71% and 74% for patients in group A (n = 157) and B (n = 137), respectively, followed up for >5 years (P = 0.27). Among the diabetic patients in both groups (191 patients), 64% discontinued the medication with insulin (P = 0.25), and 98% had stopped oral drugs within 1 year from surgery (P = 0.29). We did not observe deficiencies of vitamins and proteins. The overall incidence of incisional hernias was 38% (P = 0.35). We recorded 13 anastomotic ulcers (2.4%; P = 0.28). BPD represents, in spite of the side effects, an effective technique for treatment of morbid obesity and its associated diseases. Moreover, our results showed that patients who underwent BPD-TGR-DS had slightly better results in terms of postoperative metabolic complications and improvement in quality of life. PMID:21116732

    Background Hypothermia has been discussed as playing a role in improving the early phase of systemic inflammation. However, information on the impact of hypothermia on the local inflammatory response is sparse. We therefore investigated the kinetics of local and systemic inflammation in the late posttraumatic phase after induction of hypothermia in an established porcine long-term model of combined trauma. Materials & Methods Male pigs (35 ± 5kg) were mechanically ventilated and monitored over the study period of 48 h. Combined trauma included tibia fracture, lung contusion, liver laceration and pressure-controlled hemorrhagic shock (MAP < 30 ± 5 mmHg for 90 min). After resuscitation, hypothermia (33°C) was induced for a period of 12 h (HT-T group) with subsequent re-warming over a period of 10 h. The NT-T group was kept normothermic. Systemic and local (fracture hematoma) cytokine levels (IL-6, -8, -10) and alarmins (HMGB1, HSP70) were measured via ELISA. Results Severe signs of shock as well as systemic and local increases of pro-inflammatory mediators were observed in both trauma groups. In general the local increase of pro- and anti-inflammatory mediator levels was significantly higher and prolonged compared to systemic concentrations. Induction of hypothermia resulted in a significantly prolonged elevation of both systemic and local HMGB1 levels at 48 h compared to the NT-T group. Correspondingly, local IL-6 levels demonstrated a significantly prolonged increase in the HT-T group at 48 h. Conclusion A prolonged inflammatory response might reduce the well-described protective effects on organ and immune function observed in the early phase after hypothermia induction. Furthermore, local immune response also seems to be affected. Future studies should aim to investigate the use of therapeutic hypothermia at different degrees and duration of application.

    Purpose: To report the long-term results of the ARO 95-06 randomized trial comparing hyperfractionated accelerated chemoradiation with mitomycin C/5-fluorouracil (C-HART) with hyperfractionated accelerated radiation therapy (HART) alone in locally advanced head and neck cancer. Patients and Methods: The primary endpoint was locoregional control (LRC). Three hundred eighty-four patients with stage III (6%) and IV (94%) oropharyngeal (59.4%), hypopharyngeal (32.3%), and oral cavity (8.3%) cancer were randomly assigned to 30 Gy/2 Gy daily followed by twice-daily 1.4 Gy to a total of 70.6 Gy concurrently with mitomycin C/5-FU (C-HART) or 16 Gy/2 Gy daily followed by twice-daily 1.4 Gy to a total dose of 77.6 Gy alone (HART). Statistical analyses were done with the log-rank test and univariate and multivariate Cox regression analyses. Results: The median follow-up time was 8.7 years (95% confidence interval [CI]: 7.8-9.7 years). At 10 years, the LRC rates were 38.0% (C-HART) versus 26.0% (HART, P=.002). The cancer-specific survival and overall survival rates were 39% and 10% (C-HART) versus 30.0% and 9% (HART, P=.042 and P=.049), respectively. According to multivariate Cox regression analysis, the combined treatment was associated with improved LRC (hazard ratio [HR]: 0.6 [95% CI: 0.5-0.8; P=.002]). The association between combined treatment arm and increased LRC appeared to be limited to oropharyngeal cancer (P=.003) as compared with hypopharyngeal or oral cavity cancer (P=.264). Conclusions: C-HART remains superior to HART in terms of LRC. However, this effect may be limited to oropharyngeal cancer patients.

    Purpose the unstable osteochondritis dissecans (OCD-type II and III according to the ICRS classification) of the knee largher than > 2.5 cm2 in adults are uncommon lesions and there is no consensus on how to treat them. Medium-term studies have reported good results using autogenous osteochondral plugs (mosaicplasty). The aim of this study is to analyze the long-term results of this technique for the treatment of unstable OCD in a selected group of adult patients. Methods four patients with OCD at either one of the femoral condyles were included in this prospective study. The average age was 21.2 years (range, 18–24 years). The OCD lesions were classified as type II in three patients and type III in one patient and the average size was 3.8 cm2 (range, 2.55–5.1 cm2). The lesions were treated in situ with a variable number of autogenous osteochondral plugs (Ø 4.5 mm2). The Modified Cincinnati, Lysholm II and Tegner scores were used for clinical and functional evaluation. Magnetic resonance arthrography (MRA) was performed before surgery and at 2, 5 and 10 years after surgery. A modified MOCART score was used to evaluate MRA findings. Results the average follow-up duration was ten years and 6 months (range, 10–11 years). No complications occurred. At the final follow-up, all scores (clinical, functional and MOCART) improved. In all but one of the patients MRA showed complete osteochondral repair. Conclusions the fixation of large and unstable OCD lesions with mosaicplasty may be a good option for treating type II or III OCD lesions in adults. The advantages of this technique include stable fixation, promotion of blood supply to the base of the OCD fragment, and grafting of autologous cancellous bone that stimulates healing with preservation of the articular surface. Level of evidence Level IV, therapeutic case series. PMID:26904522

    Purpose Previous studies have shown a bidirectional relationship between diabetes and pancreatic cancer (PC). In particular, new-onset diabetes might be induced by PC, and people with long-term diabetes might be at increased risk for the development of PC. The purpose of our study was to examine whether long-term diabetes represented an independent risk factor for PC development. Methodology A literature search was performed by searching electronic databases for studies published before July 1, 2014, and relative risks (RRs) and corresponding 95% confidence intervals (CIs) were calculated. Data pertaining to diabetes were recorded at both individual and study levels, with RRs calculated separately to analyze the relationship between the duration of diabetes and the development of PC. Results Forty-four studies were included in this meta-analysis, including 18 studies with a case-control design, 5 with a nested case-control design and 21 with a cohort design. The overall summary estimate for the relationship between the population with a duration of diabetes ≥2 years and PC was 1.64 (1.52-1.78). The pooled RR (95% CI) of PC for the population with a duration of diabetes ≥5 years was 1.58 (1.42-1.75). For the population with a duration of diabetes ≥10 years, the RR (95% CI) of PC was 1.50 (1.28-1.75). Conclusions Our study suggests that long-term diabetes mellitus is associated with an increased risk of PC. However, the level of risk is negatively correlated with increasing diabetes mellitus duration. PMID:26222906

    A 54-year-old woman diagnosed with sigmoid colon cancer and multiple liver metastases underwent sigmoidectomy, partial hepatectomy, and RFA in September 2009. Because of postoperative liver and lung recurrence, 5 regimens with combinations of L-OHP/CPT-11 plus anti-VEGF antibody/anti-EGFR antibody was performed. Following these treatments, she underwent hepatic arterial infusion therapy with UFT/Krestin for progressive liver metastases. Starting in November 2014, regorafenib was administered, with an immediate decrease in tumor marker levels; tumor reduction demonstrated enhanced effect against liver metastases. After 8 months of administration, we stopped regorafenib and changed to TAS-102 due to diarrhea and eating disorders. However, TAS-102 was not effective; there were significant increases in tumor markers, liver function tests, and tumor size on computed tomography, and worsening of abdominal pain. After re-administration of regorafenib, a rapid decrease in tumor marker levels and improvement of liver dysfunction and abdominal pain were observed. Re-administration continued for 8 months until best supportive care was instituted. In cases with observed therapeutic effect of regorafenib, long-term or re-administration is possible, with extension of the prognosis depending on the adjustment, and without size reduction of metastatic tumors.

    Survivors of childhood cancer have a higher mortality than the general population. We describe cause-specific long-term mortality in a population-based cohort of childhood cancer survivors. We included all children diagnosed with cancer in Switzerland (1976-2007) at age 0-14 years, who survived ≥5 years after diagnosis and followed survivors until December 31, 2012. We obtained causes of death (COD) from the Swiss mortality statistics and used data from the Swiss general population to calculate age-, calendar year-, and sex-standardized mortality ratios (SMR), and absolute excess risks (AER) for different COD, by Poisson regression. We included 3,965 survivors and 49,704 person years at risk. Of these, 246 (6.2%) died, which was 11 times higher than expected (SMR 11.0). Mortality was particularly high for diseases of the respiratory (SMR 14.8) and circulatory system (SMR 12.7), and for second cancers (SMR 11.6). The pattern of cause-specific mortality differed by primary cancer diagnosis, and changed with time since diagnosis. In the first 10 years after 5-year survival, 78.9% of excess deaths were caused by recurrence of the original cancer (AER 46.1). Twenty-five years after diagnosis, only 36.5% (AER 9.1) were caused by recurrence, 21.3% by second cancers (AER 5.3) and 33.3% by circulatory diseases (AER 8.3). Our study confirms an elevated mortality in survivors of childhood cancer for at least 30 years after diagnosis with an increased proportion of deaths caused by late toxicities of the treatment. The results underline the importance of clinical follow-up continuing years after the end of treatment for childhood cancer. PMID:26950898

    PURPOSE We aimed to evaluate the frequency of persistence and complication rates of pulmonary arteriovenous malformations (PAVMs) treated with Amplatzer vascular plug (AVP) or Amplatzer vascular plug type 2 (AVP2). METHODS We retrospectively reviewed a total of 22 patients with 54 PAVMs between June 2004 and June 2014. We included 12 patients with 35 PAVMs who received percutaneous embolization using AVP or AVP2 only without the use of any other embolic devices. The mean follow-up was 54±24.3 months (range, 31–97 months). The primary end-points of the study were the efficacy of embolotherapy, the increase in oxygen saturation, and the persistence of PAVM on follow-up. Secondary end point was the incidence of complications. RESULTS The study included 10 female and two male patients with a mean age of 50.2±13.7 years (range, 21–66 years). All PAVMs had a simple angioarchitecture. The technical success of the procedure for PAVM occlusion was 100%. There was a significant increase in the oxygen saturation following embolotherapy (P < 0.0001). Follow-up computed tomography angiography revealed successful treatment in 34 PAVMs (97%) and failed treatment in one PAVM (3%). Twenty-three aneurysmal sacs (67%) showed complete disappearance. The failed treatment was due to persistence of PAVM caused by subsequent development of systemic reperfusion, which did not require further intervention. There were two minor complications but no major complications were encountered. CONCLUSION Embolotherapy of PAVMs using AVP or AVP2 devices is safe and effective, with high technical success rate, low persistence and complication rates, and with excellent long-term results.

    Chemical composition of soil organic carbon (SOC) is central to soil fertility. We hypothesize that change in SOC content resulting from various long-term fertilization strategies accompanies the shift in SOC chemical structure. This study examined the effect of fertilization strategies along with the time of fertilizer application on the SOC composition by 13C nuclear magnetic resonance (NMR) spectroscopy. The soils (Aquic Inceptisol) subjected to seven fertilizer treatments were collected in 1989, 1999 and 2009, representing 0, 10 and 20 years of fertilization, respectively. The seven fertilizer treatments were (1–3) balanced fertilization with application of nitrogen (N), phosphorus (P) and potassium (K) including organic compost (OM), half organic compost plus half chemical fertilizer (1/2OM), and pure chemical NPK fertilizer (NPK); (4–6) unbalanced chemical fertilization without application of one of the major elements including NP fertilizer (NP), PK fertilizer (PK), and NK fertilizer (NK); and (7) an unamended control (CK). The SOC content in the balanced fertilization treatments were 2.3–52.6% and 9.4–64.6% higher than in the unbalanced fertilization/CK treatments in 1999 and 2009, respectively, indicating significant differences in SOC content with time of fertilizer application between the two treatment groups. There was a significantly greater proportion of O-alkyl C and a lower proportion of aromatic C in the balanced fertilization than in unbalanced fertilization/CK treatments in 1999, but not in 2009, because their proportions in the former treatments approached the latter in 2009. Principal component analysis further showed that the C functional groups from various fertilization strategies tended to become compositionally similar with time. The results suggest that a shift in SOC chemical composition may be firstly dominated by fertilization strategies, followed by fertilization duration. PMID:25884713

  10. Self-contained self-rescuer long term field evaluation: combined eighth and ninth phase results

    SciTech Connect

    2006-10-15

    The National Institute for Occupational Safety and Health (NIOSH) National Personal Protective Technology Laboratory (NPPTL) and the Mine Safety and Health Administration (MSHA) conduct a Long Term Field Evaluation (LTFE) program to evaluate deployed self-contained self rescuers (SCSRs). The objective of the program is to evaluate how well SCSRs endure the underground coal mining environment with regard to both physical damage and aging when they are deployed in accordance with Federal regulations (30 CFR 75.1714). This report presents findings of the combined eighth and ninth phases of the LTFE. For these phases, over four hundred SCSRs were evaluated. The units tested include the CSE SR-100, Draeger Oxy K-Plus, MSA Life-saver 60, and the OCENCO EBA 6.5. The OCENCO 20 was evaluated only in Phase 9. Testing was performed between December 2000 and April 2004. Results of the evaluation indicate that all SCSRs experience some performance degradation due to the mining environment. Observed degradation varies from elevated levels of carbon dioxide, high breathing resistance, and reduced capacity. Mechanical degradation to the SCSR components included breathing hoses, chemical beds, outer cases and seals. The LTFE tests discussed in this report are different from tests performed for SCSR certification to the requirements of 42 Code of Federal Regulations, Part 84 (42 CFR, Part 84). LTFE tests reported here are conducted to an end point, oxygen depletion, to enable comparison of the duration of new and deployed SCSRs. The method for obtaining deployed SCSRs for this evaluation was not a random selection from the deployed population of SCSRs. Although the results of these tests are useful for observing performance of the tested SCSRs, they are not representative of all deployed SCSRs. 9 refs., 10 figs., 9 tabs., 3 apps.
