Toxicity and Outcome of Radiotherapy with Concomitant and Adjuvant Temozolomide in Elderly Patients with Glioblastoma: A Retrospective Study

Radiation therapy with concomitant and adjuvant temozolomide (TMZ) is the standard therapy for nonelderly patients with glioblastoma. However, TMZ-based chemoradiotherapy for elderly patients with glioblastoma is controversial. The aim of this study was to investigate the benefits and adverse effects of this combined therapy in elderly patients with glioblastoma. Of the 76 newly diagnosed glioblastoma patients who were treated with standard radiotherapy (60 Gy/30 fractions) and TMZ, treatment toxicity and therapeutic outcome were evaluated in 27 elderly patients (age 65 years or older) and compared with those of 49 nonelderly counterparts (age younger than 65 years). The incidence of common toxicity criteria Grade 4 adverse events during the concomitant course was higher in the elderly group than that in the nonelderly group (26% versus 8%; p = 0.046). Cognitive dysfunction was observed only in the elderly group (p = 0.042). The median overall survival (OS) and median progression-free survival in the elderly group were 15.2 months (95% confidence interval [CI]; 12.9–18.5) and 8.4 months (95% CI; 5.1–11.7), respectively. OS was significantly shorter in the elderly group than in the nonelderly group (p = 0.021). The recursive partitioning analysis score was a prognostic factor for OS. TMZ-based chemoradiotherapy was associated with an increased risk of Grade 4 adverse events in the elderly patients during concomitant use. Thus, elderly patients who undergo a concomitant course of TMZ must be closely monitored for adverse events. Treatment of glioblastoma in elderly patients must be optimized to reduce toxicity to acceptable levels and to maintain efficacy.     

Encouraging experience of concomitant Temozolomide with radiotherapy followed by adjuvant Temozolomide in newly diagnosed glioblastoma multiforme: single institution experience

The purpose of this study was to report our experience with concomitant and adjuvant temozolomide (TMZ) with radiotherapy in patients with newly diagnosed glioblastoma multiforme (GBM). Forty-two newly diagnosed histopathologically proven patients with GBM underwent maximal safe resection followed by external radiotherapy to a total dose of 60 Gy in 30 fractions over 6 weeks along with concomitant oral TMZ (75 mg/m2) daily followed by adjuvant TMZ for 5 days every 28 days for six cycles (150 mg/m2 for the first cycle and 200 mg/m2 for rest of the cycles). Patients were monitored clinicoradiologically as per standard practice. Patients were 13-69 years of age with a median age of 49.5 years (31 males, 11 females). Fifty per cent of patients underwent a gross total resection of tumour, 43% had partial resection, and 7% an open or stereotactic biopsy only. 53% of the patients had a post-operative Karnofsky Performance Score (KPS) of 60-80%. All patients received concomitant radiation and TMZ with 74% of the patients completing six cycles of adjuvant TMZ. At a median follow-up of 12.5 months, the 1- and 2-year survival was 67 and 29%, respectively. The median overall and progression-free survival was 16.4 and 14.9 months respectively. Patients with pretreatment KPS of >80% had significantly better overall survival as compared with those having KPS相似文献   

Recurrent Malignant Gliomas Treated with Radiosurgery

The inability to control malignant glioma results in a high incidence of local failure and poor survival. Focal therapy such as radiosurgery permits delivery of a high dose of radiation with moderate toxicity. This report summarizes the outcome of patients with recurrent malignant glioma treated with radiosurgery at University of Wisconsin Hospital, between January 1989 and December 1997, when 30 patients were treated radiosurgically. All patients had undergone and failed external beam radiotherapy (median dose of 59.4 Gy) prior to radiosurgery. All recurrences were detected by clinical deterioration and confirmed by radiographic progression. No patient was treated for radiographic progression only in the context of a screening protocol. Eight out of 30 patients underwent subtotal resection prior to radiosurgery and 3 received chemotherapy along with radiosurgery. Radiosurgery was delivered in a single fraction using a modified linear accelerator. The median tumor volume was 7.2 cm³ (range 0.42–35.1 cm³) and the median minimal tumor dose was 12 Gy at the 50–80% isodose line. Median follow-up is 70 months. The median overall survival is 8 months; the 1- and 2-year survival rates are 20% and 9%, respectively. For patients with an initial diagnosis of non-glioblastoma, the median survival is 11 months and for those with glioblastoma the median survival is 7 months. The median progression-free survival is 4 months for the entire cohort, 5 months for nonglioblastoma, and 3 months for glioblastoma. The 1-year actuarial reoperation rate after radio-surgery is 7.6%. Radiosurgery for recurrent malignant glioma may improve short-term survival for selected patients with a lower reoperation rate than brachytherapy.     

Squamous Cell Carcinoma of the Esophagus: Multimodal Therapy in Locally Advanced Disease

The aim of this prospective study is to report our experience in the multimodal management of locally advanced esophageal squamous cell carcinoma (LAESC; stage III cTNM), focusing on the results of chemoradiotherapy followed by surgery. These findings were compared to the results of a standard group of patients with locally advanced esophageal carcinoma (LAEC; stage III pTNM) treated in our center with surgery alone. Sixty-one patients with LAESC underwent preoperative chemoradiotherapy (5-fluorouracil + cisplatin) with concomitant 45 Gray radiotherapy in a 5-week course. Transthoracic esophagectomy was performed 4 to 5 weeks after the end of the neoadjuvant therapy. Thirty-eight patients underwent surgery, and 37 of them had resections (resectability: 97% in the multimodal group; 84% in the standard surgical series; p = 0.07). The R0 (complete) resection rate was 78% compared to 56% in the standard surgical group (p <0.03). Eleven patients had no residual tumor in the resected specimen (pathologic complete response: pCR: 30%). The operative mortality rate was 19% compared with 8.8% in the standard series. The overall median survival of the resected patients was 21 months, with a 5-year survival rate of 11% (14% in the surgical group; NS). The 3-year and 5-year survival rates were 34% for the pCR group and respectively 5% and 0% for the group with pathologic incomplete response (pIR; p <0.05). The median survival was 28 months for the pCR patients and 19 months for the pIR group. In this non-randomized trial, preoperative chemoradiotherapy in LAESC seems to increase the resectability and R0 resection rates, to allow a higher pCR rate and a longer survival only in the pCR group, at the expense of an inadequate increase in operative mortality. This multimodal treatment cannot be proposed as a standard procedure unless less toxic regimens are developed, increasing the benefits with better local and distant failure control and decreasing operative mortality.     

Complete 5-year follow-up of a prospective phase II trial of preoperative chemoradiotherapy for esophageal cancer

BACKGROUND: Conclusive evidence supporting the routine use of multimodality therapy in esophageal cancer is lacking. However, since long-term survival after esophagectomy alone is unusual, clinical trials designed to identify effective therapeutic regimens are essential. We report here the 5-year results of a phase II induction chemoradiotherapy trial. METHODS: From August 1991 to January 1995, 44 patients with esophageal or gastroesophageal junction carcinoma were treated with a combination of 5-fluorouracil, cisplatin, and interferon-alpha with concurrent external beam radiotherapy. RESULTS: Forty-one (93%) patients completed chemoradiotherapy, with most toxic events recorded as grade I or II. Curative resection (all gross tumor removed) was achieved in 36 of 37 surgical explorations, with 10 tumors demonstrating complete pathologic response and 23 showing partial pathologic response. Median follow-up for survivors was 75 months (range, 60-100 months). Five-year survival for all patients was 32%, with a median survival of 28 months. Five-year disease-free survival in patients with curative resection was 36% (median, 26 months) and overall survival was 39% (median, 34 months). Five-year survival for patients with curative resection whose disease responded to chemoradiotherapy was 42% (median overall survival, 36 months). Local-regional recurrence alone occurred in 3 patients, distant failure alone in 12 patients, and combined local-regional and distant failure in 2 patients. A Cox proportional hazards model identified both pathologic tumor and nodal stage as independent predictors of disease-free survival. Fourteen patients (32%) were 5-year survivors; 1 of these patients later experienced disease recurrence and died. CONCLUSIONS: Preoperative chemoradiotherapy can result in a long-term and durable disease-free state. Only large, multi-institutional phase III trials can determine whether combined modality therapy is superior to resection alone.     

Retrospective Analysis of Bevacizumab in Combination with Ifosfamide,Carboplatin, and Etoposide in Patients with Second Recurrence of Glioblastoma

Bevacizumab has been reported to be effective for recurrent glioblastoma. In our hospital, ifosfamide, carboplatin, etoposide (ICE) is the second-line chemotherapy for first recurrence of glioblastoma after temozolomide failure. In the present analysis, we retrospectively investigated the feasibility and effectiveness of bevacizumab combined with ICE in patients with glioblastoma at second relapse during ICE treatment. Between 2010 and 2012, tumor progressions were diagnosed in consecutive 8 patients who were treated with ICE for the first recurrence of glioblastoma. These patients were administered 3 cycles of 10 mg/kg bevacizumab every two weeks in combination with ICE treatment. The objective response rate of bevacizumab combination was 75% in Neuro-Oncology Working Group (RANO criteria), including complete response and partial response. Median progression free survival (PFS) and median overall survival (OS) after second relapse were 3.7 months (95% confidence interval [CI], 2.5–18.5 months) and 6.0 months (95% CI, 3.2–19.7 months), respectively. The 6-month PFS rates were 25% (95% CI, 0–55.0%). The median OS after initial diagnosis was 23.3 months (95% CI, 16.2–55.8 months). The grade 2 or 3 hematologic adverse events were identified in 7 of 8 patients, most of which might be due to ICE chemotherapy. The results of our retrospective analysis suggest that combination treatment with bevacizumab and ICE may be safe and beneficial in patients with recurrent glioblastoma.     

Carcinoma of the cardia and proximal third of the stomach. Results of surgical treatment in 91 consecutive patients

In the present retrospective study, 79 percent of the patients were men with a median age of 65.5 years. Of 91 patients, 84 were surgically explored. Excision of the tumor was carried out in 57 patients (63 percent) and was curative in 28 cases and palliative in 29 cases. Curative resection included proximal gastrectomy in 5 patients and total gastrectomy in 23 patients, which was extended to the spleen and distal pancreas in 18 patients. Lymph node metastases were found in 67 percent of the patients treated by resection. According to the TNM classification, 18 percent of the patients undergoing resection had stage I tumor, 28 percent had stage II tumor, 40 percent had stage III tumor, and 14 percent had stage IV tumor. The postoperative mortality rate was 16 percent for the entire series, 21 percent for patients undergoing palliative resection, and only 4 percent for patients undergoing curative resection. Three patients had an obvious anastomotic leak, one of whom died. Median survival time was 5 months for patients who had exploration only, 6 months for patients who had palliative resection, and 36 months for patients who had potentially curative resection. The 5 year actuarial survival rate was 20 percent for patients having resection and 40 percent for patients having curative resection. Survival was closely related to tumor stage. These results indicate that total gastrectomy with complete abdominal lymph node dissection can give comparatively good long-term results when performed for cure. Nevertheless, only one of three patients in this series could have a potentially curative resection. The only way to increase the curative resection rate and to improve survival is to detect the cancer at an early stage.     

Long-term survival following induction chemoradiotherapy and esophagectomy for esophageal carcinoma.

HYPOTHESIS: Long-term survival is rare in patients treated for esophageal carcinoma. Several clinical trials suggest the possibility of prolonged survival in patients who undergo induction chemoradiotherapy plus esophagectomy. DESIGN: Prospective uncontrolled study. SETTING: University hospital. PATIENTS AND METHODS: Forty-four patients with carcinoma of the esophagus or gastroesophageal junction were prospectively entered into a phase II trial of preoperative 5-fluorouracil, cisplatin, and interferon alfa with concurrent external beam radiotherapy before esophagectomy. Curative resection was performed on 36 of 41 patients who completed the induction chemoradiotherapy. RESULTS: Of the 44 patients, 17 are alive at a median follow-up of 50 months. Of these 17 patients, 15 show no evidence of recurrent disease. Of the 14 patients with long-term survival (> or =3 years), 1 patient died of disease, and another patient is alive with disease. The remaining 12 patients are alive and disease-free (median follow-up, 54 months). Six patients have survived longer than 4 years and 3 patients longer than 5 years. Subsequent primary tumors have developed in 2 patients. One patient had a recurrence at 11 months following initiation of treatment and remains disease-free 43 months postresection of a single brain metastasis. Standard clinicopathologic parameters (age, sex, histologic findings, chemoradiotherapy regimen, and clinical and pathologic stages) were not significantly associated with a survival time of 3 years or longer (Fisher exact test, 2-tailed). Although not significant, p 53 mutational status suggested long-term survival. In 11 of 14 patients who are alive with no history of recurrence, p53 genotyping demonstrated no point mutations in 10 patients. Median survival time for the long-term survivors has not been reached. CONCLUSIONS: Long-term survival can be achieved in patients with esophageal carcinoma who undergo induction chemoradiotherapy and esophagectomy. Recurrence is unlikely in patients who survive for 3 years or longer after undergoing this multimodality treatment.     

Effectiveness of maximal safe resection for glioblastoma including elderly and low karnofsky performance status patients: retrospective review at a single institute

Elderly and low Karnofsky performance status (KPS) patients have been excluded from most prospective trials. This retrospective study investigated glioblastoma treatment outcomes, including those of elderly and low KPS patients, and analyzed the prognostic factors using the medical records of 107 consecutive patients, 59 men and 48 women aged from 21 to 85 years (median 65 years), with newly diagnosed glioblastoma treated at our institute. There were 71 high-risk patients with age >70 years and/or KPS <70%. Based on the extent of resection, the patients were classified into 3 groups: more than subtotal resection (subtotal, n = 44), partial resection (partial, n = 29), and biopsy only (biopsy, n = 34). Median overall survival (OS) of all 107 patients was 13.5 months. Median OS was 13.2 months in the high-risk group. Median OSs were 15.8, 12.8, and 12.1 months in the subtotal, partial, and biopsy groups, respectively. Multivariate analysis of 73 patients in the subtotal and partial groups found age ≤65 years (p = 0.047), 60 Gy irradiation (p = 0.009), O(6)-methylguanine-deoxyribonucleic acid methyltransferase-negative (p = 0.027), and more than subtotal removal (p = 0.003) were significant prognostic factors. The median postoperative KPS score tended to be better than the preoperative score, even in the high-risk group. We recommend maximal safe resection for glioblastoma patients, even those with advanced age and/or with low KPS scores.     

Adjuvant concurrent chemoradiation for node-positive adenocarcinoma of the duodenum

HYPOTHESIS: Adjuvant chemoradiation improves local control and survival in patients with node-positive duodenal adenocarcinoma treated with pancreaticoduodenectomy. DESIGN: A retrospective review of outcomes, with a planned comparison with historical controls. SETTING: A single, high-volume academic referral center. PATIENTS: All patients with periampullary carcinoma treated with pancreaticoduodenectomy and adjuvant chemoradiotherapy at The Johns Hopkins Hospital between 1994 and 2003. Fourteen cases of node-positive duodenal adenocarcinoma were identified. Median radiation dose was 5000 cGy (range, 4000-5760 cGy). Concurrent fluorouracil-based chemotherapy was given with radiation therapy, followed by maintenance chemotherapy. RESULTS: The median follow-up was 12 months for patients who died and 42 months for those who lived. Death occurred in 7 of 14 patients (50%) during the follow-up period. Median survival for all patients was 41 months, and the 5-year survival rate was 44%. Of the 7 patients who experienced disease recurrence, 6 experienced distant metastasis as first recurrence. One of these 7 patients experienced both local recurrence and distant metastasis. Local control for all patients in the study was 93%, which compares favorably with local control reported in a series of patients treated with surgery alone (67%). Compared with historical controls treated with surgery alone, patients who received adjuvant chemoradiation therapy had an improved median survival (21 months vs 41 months, respectively). Overall 5-year survival, however, was not improved (44% vs 43%, respectively). CONCLUSION: Adjuvant chemoradiation therapy after pancreaticoduodenectomy for node-positive duodenal adenocarcinoma may improve local control and median survival but does not impact 5-year overall survival.     

Recurrence and Survival Outcomes after Hepatic Resection with or without Cryotherapy for Liver Metastases from Colorectal Carcinoma

Background Some reports support resection combined with cryotherapy for patients with multiple bilobar colorectal liver metastases (CRLM) that would otherwise be ineligible for curative treatments. This series demonstrates long-term results of 415 patients with CRLM who underwent resection with or without cryotherapy. Methods Between April 1990 and January 2006, 291 patients were treated with resection only and 124 patients with combined resection and cryotherapy. Recurrence and survival outcomes were compared. Kaplan-Meier and Cox-regression analyses were used to identify significant prognostic indicators for survival. Results Median length of follow-up was 25 months (range 1–124 months). The 30-day perioperative mortality rate was 3.1%. Overall median survival was 32 months (range 1–124 months), with 1-, 3- and 5-year survival values of 85%, 45% and 29%, respectively. The overall recurrence rates were 66% and 78% for resection and resection/cryotherapy groups, respectively. For the resection group, the median survival was 34 months, with 1-, 3- and 5- year survival values of 88%, 47% and 32%, respectively. The median survival for the resection/cryotherapy group was 29 months, with 1-, 3- and 5-year survival values of 84%, 43% and 24%, respectively (P = 0.206). Five factors were independently associated with an improved survival: absence of extrahepatic disease at diagnosis, well- or moderately-differentiated colorectal cancer, largest lesion size being 4 cm or less, a postoperative CEA of 5 ng/ml or less and absence of liver recurrence. Conclusions Long-term survival results of resection combined with cryotherapy for multiple bilobar CRLM are comparable to that of resection alone in selected patients.     

Implanted Carmustine Wafers Followed by Concomitant Radiochemotherapy to Treat Newly Diagnosed Malignant Gliomas: Prospective, Observational, Multicenter Study on 92 Cases

Objectives

Study the feasibility and effectiveness of a treatment associated surgery, intraoperative chemotherapy (carmustine wafers), and concomitant radiochemotherapy (temozolomide) for the management of newly diagnosed, high-grade gliomas.

Methods

Prospective multicenter study conducted in 17 French centers with a total of 92 patients with newly diagnosed malignant glioma treated by surgery, implanted Carmustine wafers (Gliadel^®) followed by concomitant radiochemotherapy by temozolomide (Temodar^®). Clinical, imaging, and survival data were collected to study toxicity-induced adverse events and efficacy.

Results

A total of 20.6 % presented with adverse events during surgery, potentially attributable to carmustine, including 5 severe infections. Afterwards, 37.2 % of patients showed adverse events during radiochemotherapy and 40 % during adjuvant chemotherapy by temozolomide. We report a 10.5-month, median, progression-free survival and an 18.8-month median overall survival. No significant statistical difference was observed according to age, Karnofsky Performance Scale, or grade of the tumor. A prognostic difference at the limit of the significance threshold was observed according to the extent of the resection.

Conclusions

Multimodal treatment associating implanted carmustine chemotherapy and concomitant radiochemotherapy with temozolomide seems to yield better survival rates than those usually described when carmustine or temozolomide are used alone independently from one another. These interesting results were obtained without increased adverse events and would need to be validated during a phase 3 study.     

Resection of noncolorectal nonneuroendocrine liver metastases: a comparative analysis

BACKGROUND: Although established for metastatic colorectal (CR) and neuroendocrine (NE) malignancies, the role of partial hepatectomy in management of metastases from other primaries (NCRNE) is not well-defined. STUDY DESIGN: The objective of this retrospective study is to compare outcomes after partial hepatectomy for NCRNE, NE, and CR metastases and to identify factors associated with longterm survival for patients with NCRNE diseases. Tumor characteristics, treatments, and outcomes of 360 consecutive patients undergoing resection of NCRNE (n = 82), CR (n = 245), and NE (n = 33) hepatic metastases from 1995 to 2005 were analyzed. NCRNE tumors included breast (n = 20), sarcomas (n = 19), genitourinary (n = 18), melanoma (n = 11), and other (n = 14) cancers. The start date for follow-up and survival analyses was the date of partial hepatectomy. RESULTS: For patients with NCRNE, CR, and NE tumors, there were no marked differences in postoperative mortality (4%, 4%, and 9%) or complication (30%, 42%, and 42%) rates. Median overall survival was longest for NE patients (not yet reached) versus NCRNE and CR (both 44 months) patients (p < 0.05, log-rank test). NCRNE patients had shorter disease-free survival than CR counterparts (13 versus 16 months), p < 0.05 (log-rank test). After median followup of 59 months for NCRNE patients, actuarial 5-year overall and disease-free survival was 37% and 16%, respectively, with 15 5-year survivors. Multivariable analysis suggests that interval from discovery of liver metastases to resection > 6 months (p = 0.08) and administration of chemoradiotherapy after resection (p = 0.06) might be associated with improved overall survival. CONCLUSIONS: In selected patients, resection of NCRNE liver metastases can be done safely with survival similar to CR metastases. Delay of liver resection for at least 6 months and treatment with chemoradiotherapy after resection might be associated with improved longterm survival after partial hepatectomy.     

Evaluation of post-operative complications associated with repeat resection and BCNU wafer implantation in recurrent glioblastoma

Background

Patients with glioblastoma treated with BCNU wafer implantation for recurrence frequently receive frontline chemoradiotherapy with temozolomide as part of the Stupp protocol. A retrospective investigation was conducted of surgical complications in a cohort of these patients treated at a single institution.

Methods

We searched our institutional database for patients treated between January 2006 and October 2012 who had recurrent glioblastoma previously treated with open surgery followed by the Stupp protocol and then underwent repeat resection with or without BCNU wafers for recurrent disease. Rates of select post-operative complications within 3 months of surgery were estimated.

Results

We identified 95 patients with glioblastoma who underwent resection followed by the Stupp protocol as frontline treatment. At disease recurrence (first and second recurrence), 63 patients underwent repeat resection with BCNU wafer implantation and 32 without implantation. Generally, BCNU wafer use was associated with minor to moderate increases in rates of select complications versus non-implantation—wound healing abnormalities (14.2 vs. 6.2 %), cerebrospinal fluid leak (7.9 vs. 3.1 %), hydrocephalus requiring ventriculoperitoneal shunt (6.3 vs. 9.3 %), chemical meningitis (3.1 vs. 0 %), cerebral infections (3.1 vs. 0 %), cyst formation (3.1 vs. 3.1 %), cerebral edema (4.7 vs. 0 %), and empyema formations (1.5 vs. 0 %). Performance status was well maintained post-operatively in both groups. Median progression-free survival from the time of first recurrence was 6.0 and 5.0 months, respectively.

Conclusions

The use of the Stupp protocol as frontline therapy in patients with glioblastoma does not preclude the use of BCNU wafers at the time of progression.     

Comparison of conventional surgical resection, radioactive implantation, and bypass procedures for exocrine carcinoma of the pancreas 1975-1980.

To examine the efficacy of a variety of procedures for treatment of biopsy proven exocrine adenocarcinoma of the pancreas, a retrospective review of 231 patients surgically treated at a single institution from January 1975 through December 1980 was performed. Thirty-nine patients underwent resection for cure, of which 19 were conventional resection, 33 I125 implantation, 76 biliary or GI bypass, and 83 biopsy alone, a resectability rate of 16.9%. There was one pancreatic fistula in the implant group. Median survival following implant was 8 months (0%, 30-day mortality) and, for conventional resection (n = 19), 17 months with an inhospital mortality of 16%. Median survival excluding inhospital mortality was 17 months for the conventional resection group. For bypass, median survival was 4 months (p = 0.0001 vs. conventional resection) with an inhospital mortality of 14%. Of patients discharged from hospital, 5 of 16 (31%) survived 2 years in the conventional resection group, while 4 of 132 (3%) survived 2 years in the nonresected groups. Only one patient (5% of resected) has survived 4 years in the conventional resection group, although eight others are alive and at risk in this group. Resectability rate for patients referred with adenocarcinoma of the pancreas remains low. The only long-term survivors are in those patients undergoing resection. Local implantation with I125 requires prospective evaluation because of an apparent influence on palliation without significant morbidity.     

Intérêt d’une seconde chirurgie d’exérèse dans les glioblastomes. Étude rétrospective sur quatre ans aux centres hospitalo-universitaires de Montpellier et de Nice et revue de la littérature

Background and purpose

Glioblastoma, the most common malignant primary brain tumor in adults, is usually rapidly fatal. The current care standards for newly diagnosed glioblastoma consist, when feasible, in surgical resection, radiotherapy, and chemotherapy, as described in the Stupp protocol. Despite optimal treatment, nearly all malignant gliomas recur. If the tumor is symptomatic for mass effect, repeated surgery may be proposed.

Methods

We retrospectively analyzed the survival of patients with histologically confirmed primary glioblastoma (WHO grade 4) who were operated in two centers between January 2004 and December 2007. All patients who underwent a second resection for recurrent glioblastoma were included.

Results

During this period, 320 patients were operated in the two centers, with 240 surgical resections and 80 surgical biopsies. In the surgical resection group, 8.3% (20 patients) underwent a second surgical resection for glioblastoma. The mean age was 52 years. At the end of the study, seven patients were alive. The median survival was 24 months and progression-free survival was 7.5 months.

Conclusions

The effect of resection of recurrent glioblastoma on survival has not been extensively studied. No randomized trials have been conducted. Our data were globally identical to other retrospective studies. Selected patients with recurrent glioblastoma may be candidates for repeated surgery when the situation appears favorable based on assessment of the individual patient's factors. Factors such medical history, neurological status, location of the tumor, and progression-free survival have been proven in retrospective studies to give better results.     

Surgical resection after radiochemotherapy in patients with unresectable adenocarcinoma of the pancreas

BACKGROUND: The use of chemoradiotherapy for pancreatic cancer has been advocated for its potential ability to downstage locally advanced tumors. This article reports our experience with chemoradiotherapy for patients with unresectable, locally advanced pancreatic cancer (superior mesenteric artery or celiac axis encasement). STUDY DESIGN: Since 1998, 61 patients with radiographically unresectable, pathologically confirmed pancreatic adenocarcinoma have received standard fractionation radiation therapy (total dose, 45 Gy at 1.8 Gy, 5 d/wk) with chemotherapy, which included a continuous infusion of fluorouracil (5-FU: 650 mg/m(2)/D1-D5 and D21-D25) and cisplatin (80 mg/m(2)/bolus D2 and D22). Patients with tumor response at restaging CT scan underwent surgical exploration to determine whether the tumor was resectable. RESULTS: Thirty-eight of 61 (62%) restaged patients demonstrated a disease progression. Twenty-three patients (38%) had an objective response, with, in all cases, persistence of arterial encasement. Twenty-three patients underwent exploratory operations after chemoradiotherapy, and 13 underwent standard Whipple resection. So 13 of 23 (56%) patients who had exploratory operation, or 23 of 61 (21%) patients, underwent surgical resection. With a median followup of 27 months, median survival for the resected patients was 28 months. Median survival was 11 months in the nonresponder group (n = 38) and 20 months in the group who received a palliative procedure (n = 10). CONCLUSIONS: Locally advanced, unresectable pancreatic adenocarcinoma may be downstaged by chemoradiotherapy to allow for surgical resection. Patients whose cancer becomes resectable have a median survival at least comparable with survival after resection for initially resectable pancreatic adenocarcinoma.     

Chondrosarcoma metastatic to the heart

This review summarizes the clinical manifestations and results of treatment of chondrosarcoma metastatic to the heart. Including the patient in the present report, a total of 18 patients have been reported. The most common site of cardiac metastasis was the right atrium. Dyspnea and pleuritic chest pain were the most common symptoms associated with cardiac metastases. The median time from the initial diagnosis of primary chondrosarcoma to death was 36 months, and the median time from the initiation of cardiac symptoms to death was 2 months. Treatment of primary chondrosarcoma included local radical resection in 14 patients. Treatment of cardiac metastases consisted of palliative support in 13 patients and surgical resection in 5 patients. Median survival following the development of cardiac symptoms was 2 months for patients treated nonsurgically and 18 months for those who underwent resection of cardiac metastases. The longest survival (24 and 28 months) was obtained in 2 patients with metastases confined to the heart that were successfully resected soon after development of cardiac symptoms. These results suggest that surgical resection of cardiac metastases in patients without widespread other metastases can result in substantial prolongation of life.     

The impact of improved treatment strategies on overall survival in glioblastoma patients

Background

The introduction of ALA-Fluorescence-guided surgery (FGS) followed by concomitant radiochemotherapy according to the Stupp-protocol is representative of the major changes in glioblastoma therapy in the past years. We were interested in the impact of this new first-line treatment on the overall survival of patients suffering from newly diagnosed primary glioblastoma in a retrospective single-centre study.

Method

For this retrospective analysis, data was derived from a prospective single-centre database. Patients were divided into three treatment groups: A (FGS?/radiochemotherapy?), B (FGS?/radiochemotherapy+) and C (FGS+/radiochemotherapy+). Further stratification was applied regarding MGMT-methylation status and degree of resection. Statistical analysis was performed to determine factors (treatment regime, age, gender, performance status, MGMT promoter methylation status) significantly influencing overall survival (OAS).

Results

Two hundred and fifty-three patients suffering from primary glioblastoma treated by cytoreductive surgery between 2002 and 2009 were included in this survey. Median OAS differed significantly between the treatment groups (A?=?8.8, B?=?16.6, C?=?20.1, p?<?0.01). Resection data was available in all 253 patients. The usage of FGS highly significantly correlated with a complete resection (p?<?0.01). Complete resection was positively correlated with an increase in OAS (complete 20.3 months vs. incomplete 9.3 months, p?<?0.01).

Conclusions

FGS and radiochemotherapy according to the Stupp protocol have induced an impressive improvement in overall survival in glioblastoma patients. This effect is not limited to clinical trials, but is reproducible in daily routine.     

肝、胃多原发癌的手术治疗分析:附14例报告

目的 总结分析肝、胃多原发癌的手术切除的治疗效果.方法 回顾性分析上海市东方肝胆外科医院自2004年1月至2008年1月收治的14例肝、胃多原发癌病人的手术切除资料.结果 14例病人中,12例病人一次手术同时切除肝脏及胃肿瘤,1例病人在肝脏肿瘤切除两个月后再行胃肿瘤手术治疗,另1例为胃窦腺癌术后两年发现肝脏肿瘤而行手术切除.中位生存期为23个月.术后1年、3年生存率分别为78.6%、35.7%.结论 肝、胃多原发癌由于病理特性不同,其治疗与转移癌、复发癌截然不同,两脏器肿瘤可行根治性切除,疗效与单发癌相似,采取积极的治疗是病人获得长期生存的关键.
