Peritoneal carcinomatosis (PC) is an unmet medical need. Despite recent improvements, systemic chemotherapy has limited efficacy. We report the first appli

Neuroendocrine carcinoma of the cervix (NECC) is a rare variant of cervical cancer. The prognosis of women with NECC is poor and there is no standardized therapy for this type of malignancy based on controlled trials. We performed a systematic literature search of the databases PubMed and Cochrane Central Register of Controlled Trials to identify clinical trials describing the management and outcome of women with NECC. Three thousand five hundred thirty-eight cases of NECC in 112 studies were identified. The pooled proportion of NECC among women with cervical cancer was 2303/163470 (1.41%). Small cell NECC, large cell NECC, and other histological subtypes were identified in 80.4, 12.0, and 7.6% of cases, respectively. Early and late stage disease presentation were evenly distributed with 1463 (50.6%) and 1428 (49.4%) cases, respectively. Tumors expressed synaptophysin (424/538 cases; 79%), neuron-specific enolase (196/285 cases; 69%), chromogranin (323/486 cases; 66%), and CD56 (162/267; 61%). The most common primary treatment was radical surgery combined with chemotherapy either as neoadjuvant or adjuvant chemotherapy, described in 42/48 studies. Radiotherapy-based primary treatment schemes in the form of radiotherapy, radiochemotherapy, or radiotherapy with concomitant or followed by chemotherapy were also commonly used (15/48 studies). There is no standard chemotherapy regimen for NECC, but cisplatin/carboplatin and etoposide (EP) was the most commonly used treatment scheme (24/40 studies). Overall, the prognosis of women with NECC was poor with a mean recurrence-free survival of 16 months and a mean overall survival of 40 months. Immune checkpoint inhibitors and targeted agents were reported as being active in three case reports. NECC is a rare variant of cervical cancer with a poor prognosis. Multimodality treatment with radical surgery and neoadjuvant/adjuvant chemotherapy with cisplatin and etoposide with or without radiotherapy is the mainstay of treatment for early stage disease while chemotherapy with cisplatin and etoposide or topotecan, paclitaxel, and bevacizumab is appropriate for women with locally advanced or recurrent NECC. Immune checkpoint inhibitors may be beneficial, but controlled evidence for their efficacy is lacking.

Purpose: To evaluate serum C-reactive protein (CRP) as prognostic variable in patients with epithelial ovarian cancer (EOC). Experimental Design: In a multicenter study, preoperative serum CRP was evaluated in 623 patients with EOC. Results were correlated with clinical data. Results: Mean (SD) preoperative serum CRP was 3.6 (4.8) mg/dL. Serum CRP was significantly associated with International Federation of Gynecologists and Obstetricians stage (P < 0.001) and postoperative residual tumor mass (P < 0.001) but not with histologic grade (P = 0.1) and type (P = 0.7), patients' age (Pearson's correlation coefficient = 0.05; P = 0.2), and serum CA 125 (Pearson's correlation coefficient = 0.02; P = 0.6). Patients with platinum-resistant EOC had significantly higher CRP serum levels compared with patients with platinum-sensitive EOC [6.0 (6.6) mg/dL versus 2.8 (3.8) mg/dL; P < 0.001]. Higher International Federation of Gynecologists and Obstetricians stage (P < 0.001), presence of postoperative residual tumor mass (P < 0.001), tumor grade (P = 0.001), serum CA 125 (P = 0.03), and serum CRP (P = 0.001) were independently associated with overall survival. Patients with serum CRP ≤1 mg/dL versus >1 mg/dL had an overall 5-year survival of 82% versus 58.5% (P < 0.001). Conclusion: Serum CRP can be seen as a novel, widely available independent prognostic variable of ovarian cancer.

T cell immunity toward SARS-CoV-2 spike (S-), membrane (M-), and nucleocapsid (N-) proteins may define COVID-19 severity. Therefore, we compare the SARS-CoV-2-reactive T cell responses in moderate, severe, and critical COVID-19 patients and unexposed donors. Overlapping peptide pools of all three proteins induce SARS-CoV-2-reactive T cell response with dominance of CD4⁺ over CD8⁺ T cells and demonstrate interindividual immunity against the three proteins. M-protein induces the highest frequencies of CD4⁺ T cells, suggesting its relevance for diagnosis and vaccination. The T cell response of critical COVID-19 patients is robust and comparable or even superior to non-critical patients. Virus clearance and COVID-19 survival are not associated with either SARS-CoV-2 T cell kinetics or magnitude of T cell responses, respectively. Thus, our data do not support the hypothesis of insufficient SARS-CoV-2-reactive immunity in critical COVID-19. Conversely, it indicates that activation of differentiated memory effector T cells could cause hyperreactivity and immunopathogenesis in critical patients.
