Relationship between molecular markers and lymphadenectomy and lymphovascular space invasion in endometrial cancer

Relationship between pathologic parameters, surgical parameters, or lymph node status with oncologic outcomes is not fully elucidated in endometrial cancer (EC). We want to investigate the molecular classification of uterine cancer in the Turkish population and its relationship between lymphadenectomy and lymph node metastasis. In this study, 100 patients' clinical and pathologic data diagnosed with EC were analyzed. Pathologic and molecular parameters were investigated and compared them with clinical parameters. According to the molecular analysis, 16 patients (16%) had p53 mutation, 3 patients (3%) were classified as POLE mutant group, 38 (38%) patients in the MSI group, and the remaining 43 patients (43%) into the no specific mutation profile (NSMP) group. Lymph node metastasis rate was significantly higher in copy number high (CNH) group compared to the others. In the CNH group, 29 of 437 (6.6%) dissected lymph nodes had metastasis. The median OS was the highest in the POLE group (72 months) and lowest in the CNH group (36 months). Endometrial cancer patients showed significantly different overall and disease-free survival according to the molecular subtypes and it was consistent with the literature, Lymph node metastasis risk was the highest in CNH group. MSI status is important for the lymph node metastasis risk but not all abnormalities, especially PMS2 and MLH1 expression changes showed the highest risk.

Clinical implication of preoperative psoas muscle area in endometrial cancer patients

Obesity is a significant risk factor for endometrial cancer. In contrast, sarcopenia describes a loss of the body's muscle mass that is closely related to unfavorable clinical outcomes. Even endometrial cancer patients have high rates of obesity, and they should have a significantly higher risk for undiagnosed sarcopenia or fragile muscle quality. This is a retrospective study that included an endometrial cancer database collected from a tertiary gynecologic cancer center. We investigated the relationship between preoperative psoas muscle area by magnetic resonance imaging, surgical outcomes and pathological features. The study included 116 patients, the mean height was 160 cm (Standart deviation 7), weight was 72 kg (Standart deviation 18), and the median duration of hospitalization was 4 days (Interquartile range 2-9) in the whole study group. Sarcopenia was diagnosed in 25 (21.6%) patients, according to the magnetic resonance imaging findings. Three (6.5%) obese patients had sarcopenia, but it was 31.4% in nonobese patients (p=0.026). The median duration of hospitalization was five days (3-9 days) in the sarcopenia group, and it was four days (2-7 days) in the non-sarcopenia group. Sarcopenic patients did not have increased surgical complication rates following uterine cancer surgery. We should be aware of hospitalization duration in those patients, and sarcopenic counterparts necessitate longer follow-up after the surgery.

Prognostic value of systemic inflammation response index in patients with persistent human papilloma virus infection

Persistent human papilloma virus (HPV) infection is a risk factor for the progression of cervical neoplasia into invasive carcinoma. Many inflammatory markers obtaining from hemogram parameters as platelets, monocytes, lymphocytes, and neutrophils or their ratios are still under investigation in recent decades, especially in the oncology era. Indeed, there have not been enough data about the relationship between these parameters and cervical cancer in the literature. Our primary aim was to investigate the possible relationship between the persistent HPV, which is one of the significant risk factors of cervical cancer, and these inflammatory markers. Further, we can add an easy follow-up parameter in women with persistent HPV infection. The study included patients between 30-65 years old, tested positive for HPV, and afterward had an HPV control test between January 2015 and June 2020. The study included 114 HPV DNA-positive patients. The mean age was 43 (standard deviation 8.7), and 41 of them (36%) had persistent HPV, but the remaining 73 (64%) did not. The baseline neutrophil/lymphocyte ratio (NLR) value was 2.1, platelet/lymphocyte ratio (PLR) was 133, monocyte/lymphocyte ratio (MLR) was 0.28, and systemic inflammation response index (SIRI) was 0.9. All the parameters were significantly higher in the persistent HPV group compared to the non-persistent group. Patients who had 0.65 and under this had a significantly lower risk of persistent HPV. Persistent HPV disease can be predicted with an elevated SIRI, NLR, and other hematologic parameters. So, we can closely follow up with these patients with different algorithms to prevent cervical cancer.
