- Background and ObjectiveThis study aims to investigate the impact of sex on outcome measures stratified by histological subtype in patients with resectable gastric cancer (GC).MethodsA post-hoc analysis of the CRITICS-trial, in which patients with resectable GC were treated with perioperative therapy, was performed. Histopathological characteristics and survival were evaluated for males and females stratified for histological subtype (intestinal/diffuse). Additionally, therapy-related toxicity and compliance were compared.ResultsData from 781 patients (523 males) were available for analyses. Female sex was associated with a distal tumor localization in intestinal (p = 0.014) and diffuse tumors (p < 0.001), and younger age in diffuse GC (p = 0.035). In diffuse GC, tumor-positive resection margins were also more common in females than males (21% vs. 10%; p = 0.020), specifically at the duodenal margin. During preoperative chemotherapy, severe toxicity occurred in 327 (63%) males and 184 (71%) females (p = 0.015). Notwithstanding this, relative dose intensities were not significantly different between sexes.ConclusionsPositive distal margin rates were higher in females with diffuse GC, predominantly at the duodenal site. Females also experience more toxicity, but this neither impacts dose intensities nor surgical resection rates. Clinicians should be aware of these different surgical outcomes when treating males and females with GC.

- Background. We assessed late functional and radiological pulmonary changes in breast cancer patients after a median of 11 years following radiotherapy (RT). Material and methods. Seventy women who received adjuvant loco-regional RT for breast cancer during November 1994-May 1998 accepted to participate in this follow-up study. Pulmonary function tests (PFTs) (n = 56) were compared to pre-RT examinations and diagnostic computer tomography (CT) of the lungs (n = 70) were performed and compared to four months post-RT examinations. Result. The median-matched vital capacity (VC), forced expiratory volume in one second (FEV1), and total lung capacity (TLC) were reduced 15%, 9%, and 7%, respectively, at the long-term follow-up (p < 0.001). We could not, however, detect a correlation between ipsilateral V-20 and VC-changes. Diffusion capacity (DLCO) appeared to improve compared with the pre-RT baseline level probably due to transient chemotherapy-induced toxicity. The median-matched percentage of the predicted DLCO 11 years after RT was, however, only 86%, indicating a chronic therapy-induced reduction also of this metric. According to the Arriagada classification, ipsilateral V-20 and long-term CT-changes showed a significant correlation (r(s) : 0. 57; p<0.001) in a small subset of the women. Conclusion. A chronic clinically significant reduction of PFTs compared to pre-RT values and CT-changes four months after RT were still detectable after a median follow-up of 11 years. There was a statistical correlation between V-20 and abnormalities on CT but no statistical correlation between V-20 and VC-changes.

- Background. The optimal chemotherapy in patients with advanced gastric carcinoma (GC) is yet to be determined. We compared sequential administration of docetaxel and irinotecan, both in combination with infused 5-fluorouracil/leucovorin (5-Fu/Lv), and randomly assigned patients to start with either of the two. Methods. Patients with previously untreated locally advanced or metastatic GC and with measurable lesions (response evaluation criteria in solid tumors; RECIST) were randomly assigned to start with docetaxel 45 m (arm T) or irinotecan 180 mg/m(2) (arm C) with bolus/44-h infusion of 5-Fu/Lv (day 1 every 2 weeks). After four courses, there was a pre-scheduled crossover to the alternative regimen for four additional courses. Results. Eighty-one patients were randomized and 78 started treatment. Complete and partial responses were seen in 31 (40%) patients after 8 weeks and in 32 (41%) after 16 weeks, with similar results in both study arms. The median overall survival (OS) was 11.5 and 10.6 months in arms T and C, respectively (P = 0.3). The two schedules were feasible and did not differ in the overall rate of severe adverse events (SAEs). Conclusion. This is the first randomized comparison of two of the newer cytostatic drugs in GC therapy. No differences favoring either arm T or arm C were found with respect to response rate, OS, or toxicity. The median OS of 11 months indicates that sequential administration of the two combinations is effective and is similar to triple combinations. Thus, comparable efficacy to platinum combinations appears to be obtained with newer, less toxic regimens when given sequentially.

- Background and Purpose: In this multicentre phase I-II trial we evaluated the feasibility and efficacy of capecitabine and oxaliplatin followed by the combination of these two drugs with radiotherapy in patients with locally advanced pancreatic or biliary tract cancer. Material and methods: Thirty-nine patients with inextirpable adenocarcinoma of the pancreas, gallbladder or extrahepatic bile ducts were included. Two cycles of XELOX (capecitabine 1000 mg/m(2) bid d1-14 + oxaliplatin 130 mg/m(2) d1, q3w) were followed by XELOX-RT (radiotherapy (50.4 Gy), combined with capecitabine 750-675 mg/m(2) bid every radiotherapy day and oxaliplatin 40-30 mg/m(2) once weekly). Primary end-points were tolerance (phase I) and objective response (phase II). Results: The maximum tolerated doses of oxaliplatin and capecitabine to combine with irradiation were 30 mg/m(2) and 675 mg/m(2), respectively. Twenty-one percent (95% CI: 9-38%) of evaluable patients achieved partial response. Five patients went through surgery (three R0 resections). Two-year survival was 28%, and estimated local tumour control rate at 2 years was 72%. The most common grade 3-4 toxicity was nausea and vomiting. Conclusions: XELOX-RT (30 mg/m(2) oxaliplatin/675 mg/m(2) capecitabine in combination with 50.4 Gy/28 fractions) was well tolerated and effective for locally advanced pancreatic and biliary tract cancer.

- BackgroundThe aim was to evaluate the feasibility and the effectiveness of neoadjuvant systemic chemotherapy followed by cytoreductive surgery (CRS), hyperthermic intraperitoneal chemotherapy (HIPEC) and early postoperative intraperitoneal chemotherapy (EPIC) in patients with peritoneal carcinomatosis (PC) from gastric cancer.Material and methodsEighteen patients (median age 57 years, range 38-74) were scheduled for three months' neoadjuvant systemic chemotherapy followed by CRS + HIPEC + EPIC.ResultsAt the time of surgery, the peritoneal tumor burden was extensive with tumor growth on the entire peritoneal cavity. Only eight patients received the entire treatment and OS was 14.3 months (range 6.1-34.3, 95% CI 6.6-20.3). Six patients had macroscopically radical (CC0) surgery and for this subgroup OS was 19.1 months (range 6.1-34.3, 95% CI 6.9-27.1). Postoperative 90-day mortality was 10% (one patient) and the perioperative grades II-IV adverse events (AE) rate was 62.5%.DiscussionNeoadjuvant chemotherapy followed by CRS + HIPEC + EPIC does not seem to be associated with prolonged OS in patients with extensive PC growth from gastric cancer unless macroscopically radical surgery is achieved. However, morbidity from this treatment is considerable and it cannot be recommended for routine care until a prospective randomized trial has been performed.

- Importance: The patterns of disease recurrence after resection of pancreatic ductal adenocarcinoma with adjuvant chemotherapy remain unclear.Objective: To define patterns of recurrence after adjuvant chemotherapy and the association with survival.Design, Setting, and Participants: Prospectively collected data from the phase 3 European Study Group for Pancreatic Cancer 4 adjuvant clinical trial, an international multicenter study. The study included 730 patients who had resection and adjuvant chemotherapy for pancreatic cancer. Data were analyzed between July 2017 and May 2019.Interventions: Randomization to adjuvant gemcitabine or gemcitabine plus capecitabine.Main Outcomes and Measures: Overall survival, recurrence, and sites of recurrence.Results: Of the 730 patients, median age was 65 years (range 37-81 years), 414 were men (57%), and 316 were women (43%). The median follow-up time from randomization was 43.2 months (95% CI, 39.7-45.5 months), with overall survival from time of surgery of 27.9 months (95% CI, 24.8-29.9 months) with gemcitabine and 30.2 months (95% CI, 25.8-33.5 months) with the combination (HR, 0.81; 95% CI, 0.68-0.98; P=.03). The 5-year survival estimates were 17.1% (95% CI, 11.6%-23.5%) and 28.0% (22.0%-34.3%), respectively. Recurrence occurred in 479 patients (65.6%); another 78 patients (10.7%) died without recurrence. Local recurrence occurred at a median of 11.63 months (95% CI, 10.05-12.19 months), significantly different from those with distant recurrence with a median of 9.49 months (95% CI, 8.44-10.71 months) (HR, 1.21; 95% CI, 1.01-1.45; P=.04). Following recurrence, the median survival was 9.36 months (95% CI, 8.08-10.48 months) for local recurrence and 8.94 months (95% CI, 7.82-11.17 months) with distant recurrence (HR, 0.89; 95% CI, 0.73-1.09; P=.27). The median overall survival of patients with distant-only recurrence (23.03 months; 95% CI, 19.55-25.85 months) or local with distant recurrence (23.82 months; 95% CI, 17.48-28.32 months) was not significantly different from those with only local recurrence (24.83 months; 95% CI, 22.96-27.63 months) (P=.85 and P=.35, respectively). Gemcitabine plus capecitabine had a 21% reduction of death following recurrence compared with monotherapy (HR, 0.79; 95% CI, 0.64-0.98; P=.03).Conclusions and Relevance: There were no significant differences between the time to recurrence and subsequent and overall survival between local and distant recurrence. Pancreatic cancer behaves as a systemic disease requiring effective systemic therapy after resection.Trial Registration: ClinicalTrials.gov identifier: NCT00058201, EudraCT 2007-004299-38, and ISRCTN 96397434. This secondary analysis of a randomized clinical trial investigates patterns of recurrence after adjuvant chemotherapy in pancreatic cancer and the association with survival.

Forskningsöversikt (refereegranskat)abstract
- Several phase I/II studies of chemoradiotherapy for gastric cancer have reported promising results, but the significance of preoperative radiotherapy in addition to chemotherapy has not been proven. In this study, a systematic literature search was performed to capture survival and postoperative morbidity and mortality data in randomised clinical studies comparing preoperative (chemo)radiotherapy or chemotherapy versus surgery alone, or preoperative chemoradiotherapy versus chemotherapy for gastric and/or gastro-oesophageal junction (GOJ) cancer. Hazard ratios (HRs) for overall mortality were extracted from the original studies, individual patient data provided from the principal investigators of eligible studies or the earlier published meta-analysis. The incidences of postoperative morbidities and mortalities were also analysed. In total 18 studies were eligible and data were available from 14 of these. The meta-analysis on overall survival yielded HRs of 0.75 (95% CI 0.65-0.86, P < 0.001) for preoperative (chemo)radiotherapy and 0.83 (95% CI 0.67-1.01, P = 0.065) for preoperative chemotherapy when compared to surgery alone. Direct comparison between preoperative chemoradiotherapy and chemotherapy resulted in an HR of 0.71 (95% CI 0.45-1.12, P = 0.146). Combination of direct and adjusted indirect comparisons yielded an HR of 0.86 (95% CI 0.69-1.07, P = 0.171). No statistically significant differences were seen in the risk for postoperative morbidity or mortality between preoperative treatments and surgery alone, or preoperative (chemo)radiotherapy and chemotherapy. Preoperative (chemo)radiotherapy for gastric and GOJ cancer showed significant survival benefit over surgery alone. In comparisons between preoperative chemotherapy and (chemo)radiotherapy, there is a trend towards improved survival when adding radiotherapy, without increased postoperative morbidity or mortality.
