Új adatok a korai méhnyakrák műtéti kezelésének evolúciójához

Az endoszkópos műtéti technika elterjedése a nőgyógyászatban a korai méhnyakrák műtéti kezelésében is igazolta a technológia előnyeit. A műtéti morbiditásnak, a leggyakrabban a vérveszteségnek és a sebgyógyulási zavarnak a csökkenése, valamint a kórházi ápolás és a lábadozás rövidebb időtartama hamar bebizonyosodott, azonban a kezdetben publikált túlélési eredmények jelentősen elmaradtak a nyitott műtéti technikával operált betegekéihez képest. A közelmúltban befejezett nagy esetszámú vizsgálatok eredményei alapján úgy tűnik, hogy az endoszkópos technika kurativitásának látszólagos hátránya ablasticus technikai elemek alkalmazásával és a patológiai feldolgozás alaposságának fokozásával behozható. Szoros feltételek teljesülése esetén még a szisztematikus lymphadenectomia is biztonságosan kiváltható az őrszemnyirokcsomók ’ultrastaging’ vizsgálatával. A korai méhnyakrák radikális műtéti kezelésében alkalmazott minimálisan invazív technológiának a 2018-ban bekövetkezett megtorpanása átmenetinek tekinthető. Orv Hetil. 2026; 167(7): 251–256.

Radical hysterectomy in early cervical cancer in Europe: characteristics, outcomes and evaluation of ESGO quality indicators

Comprehensive updated information on cervical cancer surgical treatment in Europe is scarce. To evaluate baseline characteristics of women with early cervical cancer and to analyze the outcomes of the ESGO quality indicators after radical hysterectomy in the SUCCOR database. The SUCCOR database consisted of 1272 patients who underwent radical hysterectomy for stage IB1 cervical cancer (FIGO 2009) between January 2013 and December 2014. After exclusion criteria, the final sample included 1156 patients. This study first described the clinical, surgical, pathological, and follow-up variables of this population and then analyzed the outcomes (disease-free survival and overall survival) after radical hysterectomy. Surgical-related ESGO quality indicators were assessed and the accomplishment of the stated recommendations was verified. The mean age of the patients was 47.1 years (SD 10.8), with a mean body mass index of 25.4 kg/m In this European cohort, the rate of adjuvant therapy after radical hysterectomy is higher than for most similar patients reported in the literature. The majority of centers were already following the European recommendations even 5 years prior to the ESGO quality indicator implementations.

SUCCOR quality: validation of ESGO quality indicators for surgical treatment of cervical cancer

To evaluate whether compliance with European Society of Gynaecological Oncology (ESGO) surgery quality indicators impacts disease-free survival in patients undergoing radical hysterectomy for cervical cancer. In this retrospective cohort study, 15 ESGO quality indicators were assessed in the SUCCOR database (patients who underwent radical hysterectomy for International Federation of Gynecology and Obstetrics (FIGO) stage 2009 IB1, FIGO 2018 IB1, and IB2 cervical cancer between January 2013 and December 2014), and the final score ranged between 0 and 16 points. Centers with more than 13 points were classified as high-quality indicator compliance centers. We constructed a weighted cohort using inverse probability weighting to adjust for the variables. We compared disease-free survival and overall survival using Cox proportional hazards regression analysis in the weighted cohort. A total of 838 patients were included in the study. The mean number of quality indicators compliance in this cohort was 13.6 (SD 1.45). A total of 479 (57.2%) patients were operated on at high compliance centers and 359 (42.8%) patients at low compliance centers. High compliance centers performed more open surgeries (58.4% vs 36.7%, p<0.01). Women who were operated on at centers with high compliance with quality indicators had a significantly lower risk of relapse (HR=0.39; 95% CI 0.25 to 0.61; p<0.001). The association was reduced, but remained significant, after further adjustment for conization, surgical approach, and use of manipulator surgery (HR=0.48; 95% CI 0.30 to 0.75; p=0.001) and adjustment for adjuvant therapy (HR=0.47; 95% CI 0.30 to 0.74; p=0.001). Risk of death from disease was significantly lower in women operated on at centers with high adherence to quality indicators (HR=0.43; 95% CI 0.19 to 0.97; p=0.041). However, the association was not significant after adjustment for conization, surgical approach, use of manipulator surgery, and adjuvant therapy. Patients with early cervical cancer who underwent radical hysterectomy in centers with high compliance with ESGO quality indicators had a lower risk of recurrence and death.

SUCCOR cone study: conization before radical hysterectomy

To evaluate disease-free survival of cervical conization prior to radical hysterectomy in patients with stage IB1 cervical cancer (International Federation of Gynecology and Obstetrics (FIGO) 2009). A multicenter retrospective observational cohort study was conducted including patients from the Surgery in Cervical Cancer Comparing Different Surgical Aproaches in Stage IB1 Cervical Cancer (SUCCOR) database with FIGO 2009 IB1 cervical carcinoma treated with radical hysterectomy between January 1, 2013, and December 31, 2014. We used propensity score matching to minimize the potential allocation biases arising from the retrospective design. Patients who underwent conization but were similar for other measured characteristics were matched 1:1 to patients from the non-cone group using a caliper width ≤0.2 standard deviations of the logit odds of the estimated propensity score. We obtained a weighted cohort of 374 patients (187 patients with prior conization and 187 non-conization patients). We found a 65% reduction in the risk of relapse for patients who had cervical conization prior to radical hysterectomy (hazard ratio (HR) 0.35, 95% confidence interval (CI) 0.16 to 0.75, p=0.007) and a 75% reduction in the risk of death for the same sample (HR 0.25, 95% CI 0.07 to 0.90, p=0.033). In addition, patients who underwent minimally invasive surgery without prior conization had a 5.63 times higher chance of relapse compared with those who had an open approach and previous conization (HR 5.63, 95% CI 1.64 to 19.3, p=0.006). Patients who underwent minimally invasive surgery with prior conization and those who underwent open surgery without prior conization showed no differences in relapse rates compared with those who underwent open surgery with prior cone biopsy (reference) (HR 1.94, 95% CI 0.49 to 7.76, p=0.349 and HR 2.94, 95% CI 0.80 to 10.86, p=0.106 respectively). In this retrospective study, patients undergoing cervical conization before radical hysterectomy had a significantly lower risk of relapse and death.

Decoding the Molecular Landscape of 262 Uterine Sarcomas: RNA-Seq Clustering of ESS, UTROSCT, and UUS with Prognostic Insights.

Low-grade endometrial stromal sarcomas (LG-ESS), high-grade ESS (HG-ESS), undifferentiated uterine sarcomas (UUS), and uterine tumors resembling ovarian sex cord tumors are distinct non-smooth muscle cell neoplasms with varying clinical outcomes, often exhibiting overlapping characteristics. Diagnosis can be supported by identifying characteristic recurrent translocations, which may be absent in some cases, complicating the distinction of equivocal cases. Additionally, cases with overlapping features of low-grade and high-grade characteristics are recognized. To address these challenges, we analyzed RNA-seq profiles of 262 cases. Our results revealed that LG-ESS, with and without recurrent fusions, clustered into 2 partially overlapping expression profiles associated with distinct overall and relapse-free survival outcomes, with the cluster containing a majority of fusion-negative tumors demonstrating better prognoses. uterine tumors resembling ovarian sex cord tumors expression profiles closely resembled those of both LG-ESS subgroups, with NCOA3 fusion-positive cases clustering in groups with better survival outcomes. Furthermore, a distinct cluster for HG-ESS with BCOR and YWHAE fusions was identified, differentiating these tumors from HG-ESS without fusions. ONECUT3 emerged as a potential specific marker for this HG-ESS-fusion entity. A significant expression overlap was observed between monomorphic HG-ESS without fusions and pleomorphic UUS. These samples separated further into 2 mixed clusters distinguished by differences in immune activity, which significantly influenced overall survival and relapse-free survival outcomes. Unsupervised clustering of UUS revealed subgroups resembling either HG-ESS or muscle-cell-differentiated tumors, suggesting that UUS may include poorly differentiated distinct entities, such as leiomyosarcoma, and that the distinction from HG-ESS may, in some cases, be arbitrary. Our transcriptome analysis highlights several entities with distinct survival characteristics, providing a foundation for further characterization of these rare, often difficult-to-classify, tumors.

SUCCOR 10 years: a decade's perspective on radical hysterectomy outcomes in cervical cancer.

Interest in long-term outcomes of radical hysterectomy for cervical cancer has increased, especially after the LACC trial findings, which showed worse outcomes for minimally invasive surgery. However, limited information is available on 10-year oncological outcomes, particularly, recurrence and survival. The primary objective of this study was to analyze the 10-year oncological outcomes of patients with International Federation of Gynecology and Obstetrics 2009 stage IB1 cervical cancer treated with radical hysterectomy performed via minimally invasive or open approaches. This retrospective, multi-center, observational study updates the data from the SUCCOR cohort. Patients diagnosed between January 2013 and December 2014 with tumors ≤4 cm without extra-cervical metastasis and treated with radical hysterectomy as the primary treatment were included, and a 10-year follow-up after surgery was successfully conducted. A total of 556 patients were analyzed. The median age was 46 years (range; 18-82). The most common final International Federation of Gynecology and Obstetrics 2009 stage was IB1, 474 patients (85%), and the most common histology was squamous carcinoma, 376 patients (67.6%). The 5-year disease-free survival was 93%, and the 10-year disease-free survival was 90%. The overall survival was 97% at 5 years and 89% at 10 years. During follow-up, 9% (n = 49) of patients experienced recurrences, 78% (n = 38) within the first 5 years. Comparing surgical approaches, 10-year disease-free survival was 92% for minimally invasive surgery and 88% for open surgery (p = .12). Similarly, 10-year overall survival was 92% for minimally invasive surgery and 88% for open surgery (p = .12). Post-recurrence disease-specific survival was 47% at 60 months and 39% at 96 months. The 2-year survival after recurrence was 80% for late recurrences (>5 years) versus 69% for early recurrences. The overall survival after radical hysterectomy at 5-years was 97% in patients with early-stage cervical cancer. The recurrence rate at 10 years was 9%. No differences in 10-year survival were observed between the surgical approaches.

Prognostic Value of Conization and Negative HPV After Conization in AIS and Early Stage Cervical Cancer

In women with cervical cancer -Squamous cell carcinoma, Adeno carcinoma, Adeno-squamous carcinoma or AIS we want to examine prospectively: 1. Examine if negative HR-HPV after conization to the HR-HPV the women had before conization has a high prognostic value for no residual tumor in the final pathology. 2. To examine if conization in women with cervical tumor up to Stage I B 2 (FIGO 2018) is corelated with better prognosis.
