Does neoadjuvant chemotherapy reduce surgical complexity in patients with advanced-stage epithelial ovarian cancer?
Abstract Background This study aimed to determine the effect of neoadjuvant chemotherapy (NACT) on the complex surgical procedures required in addition to staging surgery for the need to achieve a residual tumor 1 cm or less in a population of stage IIIC–IV epithelial ovarian cancer patients. Methods Patients were referred for NACT if preoperative imaging and/or intraoperative evaluation confirmed that it was not possible to achieve a residual tumor size of 1 cm or less with cytoreductive surgery or if the patient had a poor performance status and a high American Society of Anesthesiologists (ASA) score. Surgical complexity was defined as complex or non-complex. Results One hundred and twenty-six patients with stage IIIC–IV ovarian cancer were included in the study. Primary cytoreductive surgery was performed in 67 patients, and interval cytoreductive surgery was performed in 59 patients after NACT. At least one complex surgery was performed in 74.6% of the patients in the primary cytoreductive surgery group and in 61% of the patients in the NACT group, with no statistically significant difference between the groups. However, the NACT group showed significantly decreased rates of low-rectal resection, diaphragmatic peritoneal stripping, and peritonectomy. Conclusions The analyses showed no reduction in the requirement for at least one complex surgical procedure in the group of patients who underwent NACT. Nevertheless, this group exhibited a significant decrease in low-rectal resection, diaphragmatic peritoneal stripping, and peritonectomy due to their effectiveness in reducing peritoneal disease.
Prognostic value of systemic inflammatory response markers in cervical cancer
We investigated the association between preoperative ratios of inflammatory markers and the prognosis in patients with invasive cervical cancer (CC). In this single-centre study, we retrospectively enrolled 163 CC patients who underwent radical hysterectomy between February 2008 and October 2018. Among the evaluated ratios, a high neutrophil-to-lymphocyte ratio (N/L) was significantly associated with deep stromal invasion and tumour size larger than 2 cm, whereas a high M/L was significantly related to advanced-stage CC (IB3-IIIC2), lymphatic metastasis (total) and pelvic lymph node metastasis (
Impact of postoperative infection on changes in leucocyte levels in early postoperative period in patients undergoing splenectomy during cytoreductive surgery for gynaecological malignancy
In cytoreductive surgery for gynecological cancers, 13-25% of patients require splenectomy. Therefore, hematological parameters change in the post-splenectomy period, especially leucocytosis and thrombocytosis. In this study, we aimed to evaluate the changing of leucocyte and neutrophil between the groups with and without infection in the early postoperative period in patients who underwent splenectomy during cytoreductive surgery for gynecological cancer. This retrospective study included 96 patients who underwent splenectomy during cytoreductive surgery for gynecological malignancies. Leukocyte levels, CRP, procalcitonin, and platelet counts were recorded daily during the first five postoperative days. Postoperative infections were identified based on clinical and laboratory findings. Postoperative infection was observed in 23 patients (24.0%). On postoperative day 4, the mean leukocyte count was 13.2±4.5 ×10³/µL in infected patients vs. 9.8±3.2 ×10³/µL in non-infected patients (p=0.01). By day 5, leukocyte levels remained significantly elevated in the infection group (p<0.05). Leukocyte trends, especially between days 4 and 5, may serve as a practical marker for early postoperative infection in patients undergoing splenectomy during cytoreductive surgery.
Surgery for patients with endometrioid-type endometrial cancer: is lymphadenectomy above the inferior mesenteric artery necessary?
The primary objective of this study was to identify the risk of metastasis to lymph nodes above the inferior mesenteric artery (IMA) in endometrioid-type endometrial cancer (EC) and the factors that influence metastasis. The study included patients who had been operated on for endometrioid-type EC in three gynecological oncology centers between 2007 and 2023. The supramesenteric lymph node (SM-LN) is the region between the left renal vein and the IMA, whereas the inframesenteric lymph node (IM-LN) is the region between the IMA and the aortic bifurcation, as determined by the level of the IMA. The study sample comprised 412 patients. The median number of lymph nodes excised per patient was 58. The median count was 37 for pelvic lymph nodes, 21 for para-aortic lymph nodes, 8 for IM-LN, and 13 for SM-LN. In the univariate analysis, the factors that were found to be statistically significant in determining SM-LN metastasis included tumor size, depth of myometrial invasion, uterine serosal invasion, lymphovascular space invasion (LVSI), cervical invasion, peritoneal cytology, adnexal metastasis, omental metastasis, non-nodal extrauterine metastasis, pelvic lymph node metastasis, and IM-LN metastasis. In the multivariate analysis, SM-LN metastasis was independently associated with tumor size, LVSI, pelvic lymph node metastasis, and IM-LN metastasis. In conclusion, in cases of intermediate-high risk EC, it is important to know that the disease spreads to SM-LN in 7.3% of patients. The efficacy of postoperative adjuvant treatment may be inadequate due to a lack of information regarding the SM-LN region.
Does HPV‐18 co‐infection increase the risk of cervical pathology in individuals with HPV‐16?
Abstract Objective We aimed to investigate differences between HPV‐16 mono‐ and HPV‐16/18 co‐infections in terms of cervical dysplasia and invasive cancer. Methods This multicentre, retrospective study spanned from December 2017 to December 2020, involving women who visited gynaecological oncology clinics for colposcopy with either HPV‐16 or HPV‐16/18 positivity. A total of 736 patients, 670 in Group 1 (HPV‐16 positivity) and 66 in Group 2 (HPV‐16/18 positivity), were compared for the presence of CIN2+ lesions detected by colposcopic biopsy or endocervical curettage (ECC). Exclusions included hysterectomized patients, those with prior gynaecological cancers, and patients with HPV positivity other than types 16 and 18. Results Among the included patients, 42.4% had a diagnosis of CIN2+ lesions. The cytology results demonstrated abnormal findings in 45.3% in Group 1 and 42.2% in Group 2, with no significant difference between the groups. ECC revealed CIN2+ lesion in 49 (8.7%) patients in group 1, while only 1 (1.7%) patient had CIN2+ lesion in group 2. There was no difference between 2 groups in terms of ECC result ( p = 0.052). In group 1, 289 (43.1%) patients had CIN2+ lesion, while 23 (34.8%) patients had CIN2+ lesions in group 2. There was no difference between group 1 and 2 in terms of diagnosis of CIN2+ lesions ( p = 0.19). Conclusion This multicentre retrospective study found no significant differences between HPV‐16 mono‐ and HPV‐16/18 co‐infections regarding cervical pathologies. Larger studies are needed to validate and further explore these findings.
