Preoperative neoadjuvant chemotherapy (NAC) can significantly reduce tumour burden in patients with primarily unresectable chemosensitive tumours, allowing a more complete cytoreduction during debulking surgery and facilitating evaluation of tumour chemosensitivity, identification of appropriate treatment options and improvement of intervention protocols. In this study, we investigate, using immunohistochemistry, the impact of platinum/taxane-based NAC (NAC) on tumour-infiltrating lymphocytes (TILs) in advanced epithelial ovarian cancer (EOC) and their relationship with clinical outcome. All patients had clinical response, as shown by ascites volume and CA125 levels compared to pre-treatment findings. NAC intervention significantly increased CD4(+), CD8(+) and granzyme B(+) infiltration while Foxp3(+) accumulation remained unaffected. TILs were prognostically neutral for both progression-free survival (PFS) and overall survival (OS) before NAC. In contrast, after NAC, elevated granzyme B(+) infiltration displayed a tendency for improved PFS (log-rank 0.064). Further, low Foxp3(+) cell density was associated with longer PFS, as compared with strong Foxp3(+) infiltration (median 20.94 vs. 11.24 months; log-rank 0.0001) and with improved OS (median 30.75 vs. 16.04 months, respectively; log-rank 0.056), demonstrating clear prognostic significance for PFS. In addition, high granzyme B(+)/Foxp3(+) ratio post-NAC strongly correlated with improved PFS compared to low granzyme B(+)/Foxp3(+) cell ratio (median 17.88 vs. 11.24 months, respectively), and showed to be a favourable prognostic factor for PFS (log-rank 0.014). Our findings indicate that NAC elicited an immunologic profile in which low immunosuppressive Foxp3(+) infiltration and elevated numbers of activated granzyme B(+) cells were significantly associated with EOC-specific PFS, suggesting a contribution of immunologic effects to improved clinical outcome.

It is concluded that exogenous GLP-1 effectively lowers plasma glucose concentrations in advanced type 2 diabetes long after sulfonylurea secondary failure. These findings may broaden the applicability of GLP-1-derived drugs as a new treatment to nearly all type 2 diabetic patients.

Immunostaining with D2-40 significantly increased the frequency of detection of lymphatic invasion compared to conventional H.E.-staining in early breast cancer. As LVI is a strong predictive and prognostic marker, the monoclonal antibody D2-40 has the potential to play a significant role in pathological routine workup of breast tumors. Further prospective studies are needed to prove the clinical impact of D2-40.

In a randomized clinical trial, needlescopic 3-trocar cholecystectomy was compared with transvaginal/transumbilical hybrid—NOTES—technique for symptomatic cholecystolithiasis. We found significantly less pain despite less analgesics, increased satisfaction with the aesthetic result, and improved postoperative quality of life in the NOTES group. Furthermore, both techniques were equal in terms of safety.

D2-40-based LVI assessment improves the histopathological detection of lymphovascular invasion in endometrial cancer. Furthermore, LVI is of prognostic value and predicts lymph node metastasis. D2-40 LVI detection might help to select endometrial cancer patients who will benefit from a lymphadenectomy.
