Background: Ovarian, fallopian tube, and primary peritoneal cancers often share clinical characteristics and are typically diagnosed at advanced stages due to nonspecific symptoms. The utility of tumor markers, particularly CA125 and HE4, in the diagnosis and follow-up of these cancers remains an area of active investigation. Objectives: The CEEGOG (Central and Eastern European Gynecologic Oncology Group) OX-01 study aimed to evaluate HE4's role alongside CA125 in follow-up for advanced-stage ovarian, fallopian tube, and primary peritoneal cancers. It assessed the potential for detecting recurrence using marker elevation and imaging methods, examining the necessity of dynamic monitoring and current cut-off values' accuracy for early relapse detection. Methods: In this multicenter prospective cohort study, 117 eligible patients with Stage III-IV cancers were included. Patients had elevated CA125 or HE4 at diagnosis and achieved complete remission after first-line treatment. HE4 and CA125 levels were monitored every 3-4 months in the first two years and every six months thereafter. CT scans were performed if markers exceeded set thresholds or increased by over 20%. Results: During a median follow-up of 13.7 months, 73% of patients relapsed. Median HE4 levels were significantly higher in relapsed patients. A 10 IU/mL increase from baseline in CA125 had a sensitivity of 83% and specificity of 93%, while a 15 pmol/L increase in HE4 had a sensitivity of 74% and specificity of 92% for predicting relapse up to three months before CT scan detection. Conclusions: The study found that dynamic changes in HE4 and CA125 levels, rather than predefined cut-off values, are crucial for early relapse detection. These markers may offer a significant lead time over imaging, potentially enabling earlier intervention. Further research is needed to validate these findings.

OBJECTIVE: Patients with TNM T1a cervical cancer have excellent prognosis; however, the risk for recurrence remains an issue of concern and management guidelines are based on limited data. Here we performed subgroup analysis of the Surveillance in Cervical Cancer (SCCAN) consortium with the objective of defining the prognosis of T1a cervical cancer patients. METHODS: SCCAN was an international, multicentric, retrospective cohort study of patients with cervical cancer undergoing surgical treatment in tertiary centers. Inclusion criteria included: histologically confirmed cervical cancer treated between 2007 and 2016; TNM T1a; primary surgical management; and at least 1-year of follow-up data availability. Exclusion criteria included treatment with primary chemo-radiation, and missing treatment-related or clinical data. RESULTS: Out of 975 patients included, 554 (57 %) were T1a1 and 421 (43 %) T1a2. The majority had squamous-cell carcinoma (78 %). 79 patients (8.1 %) had lymphovascular space invasion (LVSI). 455 patients (47 %) underwent radical hysterectomy/ parametrectomy. Laparoscopic and open surgery was performed in 401 (41 %) and in 361 (37 %) patients, respectively. Adjuvant treatment was administered to 56 patients (5.7 %). Assessment of lymph nodes (LN) was performed in 524 patients (54 %), with LN involvement found in 15 (2.9 %). There were 40 (4.1 %) recurrences, occurring at a median of 26 months (4-106), out of which 33 (82.5 %) occurred in pelvis. Among T1a1 cases, there were 10 recurrences (2.0 %) if LVSI was negative, and 3 recurrences (6.7 %) if LVSI was positive. Among T1a2 cases, there were 23 recurrences (6.7 %) if LVSI was negative, and 4 recurrences (5.1 %) if LVSI was positive. There were 3 recurrences in the LN+ group (recurrence rate 20 %). CONCLUSIONS: The risk of recurrence in T1a cervical cancer was 4.1 % corresponding to the rates seen in patients with FIGO 1B cancer in recently published prospective trials. LN involvement represents a risk factor for disease recurrence. Our results indicate that stage T1a cervical cancer, apart from T1a1 LVSI negative disease, should follow the same principles in the management as that of FIGO stage 1B cancer.

AIM: The aim of this study was to assess whether the use of sentinel lymph node (SLN) in addition to lymphadenectomy was associated with survival benefit in patients with early-stage cervical cancer. METHODS: International, multicenter, retrospective study. INCLUSION CRITERIA: cervical cancer treated between 01/2007 and 12/2016 by surgery only; squamous cell carcinoma, adenocarcinoma, adenosquamous carcinoma, FIGO 2009 stage IB1-IIA2, negative surgical margins, and laparotomy approach. Patients undergoing neo-adjuvant and/or adjuvant treatment and/or with positive para-aortic lymph nodes, were excluded. Women with positive pelvic nodes who refused adjuvant treatment, were included. Lymph node assessment was performed by SLN (with ultrastaging protocol) plus pelvic lymphadenectomy ('SLN' group) or pelvic lymphadenectomy alone ('non-SLN' group). RESULTS: 1083 patients were included: 300 (27.7 %) in SLN and 783 (72.3 %) in non-SLN group. 77 (7.1 %) patients had recurrence (N = 11, 3.7 % SLN versus N = 66, 8.4 % non-SLN, p = 0.005) and 34 (3.1 %) (N = 4, 1.3 % SLN versus N = 30, 3.8 % non-SLN, p = 0.033) died. SLN group had better 5-year disease-free survival (DFS) (96.0 %,95 %CI:93.5-98.5 versus 92.0 %,95 %CI:90.0-94.0; p = 0.024). No 5-year overall survival (OS) difference was shown (98.4 %,95 %CI:96.8-99.9 versus 96.8 %,95 %CI:95.4-98.2; p = 0.160). SLN biopsy and lower stage were independent factors associated with improved DFS (HR:0.505,95 %CI:0.266-0.959, p = 0.037 and HR:2.703,95 %CI:1.389-5.261, p = 0.003, respectively). Incidence of pelvic central recurrences was higher in the non-SLN group (1.7 % versus 4.5 %, p = 0.039). CONCLUSION: Adding SLN biopsy to pelvic lymphadenectomy was associated with lower recurrence and death rate and improved 5-year DFS. This might be explained by the lower rate of missed nodal metastasis thanks to the use of SLN ultrastaging. SLN biopsy should be recommended in patients with early-stage cervical cancer.

Cíl: Ucelený přehled operační léčby recidivujících zhoubných gynekologických nádorů. Recidivy zhoubných nádorů prsu nebyly do práce zařazeny. Metodika: Práce podávající přehled o možnostech operační léčby u recidivujících karcinomů děložních adnex (vaječník, vejcovod), děložního těla, hrdla, karcinomu pochvy a vulvy. Závěr: Optimální operační léčba pacientek s recidivujícím zhoubným nádorem je založena na multidisciplinárním přístupu se stratifikací podle individuálních prognostických markerů. K nim patří celkový stav pacientky, výsledek primárního operačního výkonu, aktuální rozsah recidivy, histopatologické a molekulárně biologické charakteristiky nádoru. Rozhodnutí o operačním výkonu by mělo být individuálně posuzováno multioborovou onkogynekologickou komisí.

Objective: A comprehensive overview of surgical treatment of recurrent gynecological malignancies. Recurrent breast malignancies are not included in this review. Methodology: A review providing overview of surgical treatment options for recurrent malignancies of adnexa of the uterus (ovary, fallopian tube), uterine corpus, uterine cervix, and carcinoma of the vagina and vulva. Conclusion: Optimal surgical treatment for patients with recurrent cancer is based on multidisciplinary approach with stratification according to individual prognostic markers. These include patient’s performance status, outcome of primary surgery, current extent of recurrence, and histopathological, molecular, and biochemical characteristics. Decision about choice of treatment should be individually discussed and evaluated by the multidisciplinary oncogynecological commission board.

BACKGROUND: Breast cancer is the most commonly occurring cancer worldwide and is the main cause of death from cancer in women. Novel biomarkers are highly warranted for this disease. OBJECTIVE: Evaluation of novel long non-coding RNAs biomarkers for breast cancer. METHODS: The study comprised the analysis of the expression of 71 candidate lncRNAs via screening, six of which (four underexpressed, two overexpressed) were validated and analyzed by qPCR in tumor tissues associated with NST breast carcinomas, compared with the benign samples and with respect to their clinicopathological characteristics. RESULTS: The results indicated the tumor suppressor roles of PTENP1, GNG12-AS1, MEG3 and MAGI2-AS3. Low levels of both PTENP1 and GNG12-AS1 were associated with worsened progression-free and overall survival rates. The reduced expression of GNG12-AS1 was linked to the advanced stage. A higher grade was associated with the lower expression of PTENP1, GNG12-AS1 and MAGI2-AS3. Reduced levels of both MEG3 and PTENP1 were linked to Ki-67 positivity. The NRSN2-AS1 and UCA1 lncRNAs were overexpressed; higher levels of UCA1 were associated with multifocality. CONCLUSIONS: The results suggest that the investigated lncRNAs may play important roles in breast cancer and comprise a potential factor that should be further evaluated in clinical studies.
