- Background: Early trials have reported a beneficial effect from tamoxifen treatment in patients with unresectable pancreatic cancer, in particular in women. However, the presence and prognostic significance of female hormone receptors in pancreatic or other periampullary cancers has not yet been described. Methods: Immunohistochemical screening of normal and malignant pancreatic tissue revealed that the predominantly expressed female hormone receptor was the progesterone receptor (PgR), in particular in the cancer-associated stroma. The impact of PgR expression on overall survival (OS) was further examined on tissue microarrays with primary tumours from a consecutive retrospective cohort of 175 patients with resected periampullary adenocarcinoma. Results: Median follow-up time was 29.7 (range 1.9–185.1) months. Stromal PgR positivity (PgR+), allover denoted in 31% of the cases, was significantly higher in pancreatobiliary-type than in intestinal-type tumours (38.7% vs 19.0%, p = 0.008), with an equal distribution between sexes. Stromal PgR+ was significantly associated with a prolonged OS in KRAS-mutated tumours, whereas the opposite was seen in KRAS wild-type tumours (p for interaction =0.015). This association was particularly evident in women, with a median OS of 60.5 months for PgR+/KRAS mutated tumours and 9.9 months for PgR+/KRAS wild-type tumours (p for interaction <0.001). PgR expression was not prognostic in male patients. Conclusions: The finding of stromal PgR expression, and its link to clinical outcome in a considerable proportion of pancreatic and other periampullary cancers is novel. The concept of tamoxifen treatment for patients with unresectable disease, in particular elderly women, should be pursued, and PgR and KRAS may be relevant biomarkers for improved patient stratification.

- Background: Patients with newly diagnosed mHSPC have a poor prognosis with a 3-year overall survival (OS) rate of 50%. Recently, combination of docetaxel (75mg/m2 every 6 weeks for 6 cycles) with ADT has become a new standard for such patients, based on results of 2 large phase 3 trials showing a significant OS benefit. In these trials, docetaxel was initiated within 3 months after ADT start. Timing of ADT and chemotherapy (CT) is controversial. In breast cancer, endocrine therapy is always started after CT, the rational being that ADT will turn clones of tumor cells in to a stage of dormancy where CT is less effective.Methods: This phase 3 trial randomized newly diagnosed mHSPC patients to receive cabazitaxel (CABA), 25 mg/m2 every 3 weeks for 10 cycles, followed by ADT (immediately after last CABA cycle) versus ADT alone. Primary end-point was OS. Secondary end-point was progression free survival. The study planned to include 400 patients but was closed prematurely due to low inclusion rate. A total 31 patients with newly diagnosed mHSPC were included and here we present the results.Results: Median follow up was 31 month. Of the CABA treated patients, 66.8% got six cycles or more and 46.7% completed all 10 courses. Median OS was 32,5 months with CABA followed by ADT and 29,5 months with ADT alone (HR 1.43, 95% CI 0.38-5.38). Median progression free survival was significantly longer in CABA treated patients (29 vs 12 months, HR 3.96 (95% CI 1.49-10.49). Main grade ≥ 3 toxicities were neutropenia (66%).Conclusions: In conclusion, results from this prematurely terminated trial suggest that CABA followed by ADT is effective in newly diagnosed mHSPC and shows a manageable toxicity. These results have to be validated in larger randomized trials.

- Background: Obesity is a well-established risk factor for colorectal cancer (CRC), but whether this risk differs according to CRC subtype defined by the tumor immune microenvironment has been sparsely described. Herein, we examined the relationship between pre-diagnostic anthropometry and CRC risk according to tumor-infiltrating immune cell composition, with particular reference to potential sex differences. Methods: The density of immune cells expressing PD1, PD-L1 (PD-L1/IC), CD3, CD8, FoxP3, CD20, CD68, CD163, and tumor cells expressing PD-L1 (PD-L1/TC) was assessed by immunohistochemistry in tissue microarrays with tumors from 584 incident CRC cases in the Malmö Diet and Cancer Study (n = 28098). Multivariable Cox regression models, adjusted for age, smoking and alcohol intake, were applied to calculate hazard ratios (HR) for CRC risk according to height, weight, bodyfat %, waist- and hip circumference, waist-hip ratio (WHR), body mass index (BMI), and different immune cell subsets. Results: Obesity, measured as several anthropometric factors, was significantly associated with PD-L1+/TC low, CD8+ high, FoxP3+ low, CD20+ low, and CD163+ low tumors in both sexes, and with PD1+ low tumors in women. A contrasting risk between sexes was seen for PD-L1/IC+ tumors, in that obesity was significantly associated with risk of PD-L1/IC+ high tumors in women (ptrend for weight = 0.008, ptrend for BMI = 0.039), but with risk of PD-L1/IC+ low tumors in men (ptrend for weight = 0.005, ptrend for bodyfat % = 0.003, ptrend for waist <0.001, ptrend for hip = 0.012, ptrend for BMI = 0.001, ptrend for WHR <0.001). Furthermore, obesity was associated with risk of any CD3+ high or low and any CD68+ high or low tumors in both sexes, and with any PD1+ high or low tumors in men. In age and BMI-adjusted survival analysis, PD1+, CD8+, CD20+, and CD68+ high were favorable prognostic factors only in women, and FoxP3+ high only in men. High PD-L1+ and CD3+ expression was prognostic in both sexes. Conclusions: Anthropometric factors may influence the immune landscape of colorectal cancer, possibly in a sex-dependent manner. Thus, obesity and sex may be important factors to take into account when stratifying patients for immunotherapy.
