Impact of various treatment modalities on the outcome of stage IB1-IIA cervical adenocarcinoma

Treatment for Locally Resectable Stage IIIC1 Cervical Cancer: A Retrospective, Single-Institution Study

According to the revision of the FIGO 2018 staging system, cervical cancer with pelvic lymph node metastases was changed to stage IIIC1. We retrospectively analyzed the prognosis and complications of locally resectable (classified as T1/T2 by TNM classification of the Union for International Cancer Control) stage IIIC1 cervical cancer. A total of 43 patients were divided into three groups: surgery with chemotherapy (CT) (ope+CT group) (T1; n = 7, T2; n = 16), surgery followed by concurrent chemoradiotherapy (CCRT), or radiotherapy (RT) (ope+RT group) (T1; n = 5, T2; n = 9), and CCRT or RT alone (RT group) (T1; n = 0, T2; n = 6). In T1 patients, recurrence was observed in three patients, but there was no difference among the treatment groups, and no patients died. In contrast, in T2 patients, recurrence and death were observed in nine patients (8 in ope+CT; 1 in ope+RT), and recurrence-free survival and overall survival were lower in the ope+CT group (p = 0.02 and 0.04, respectively). Lymphedema and dysuria were more common in the ope+RT group. A randomized controlled trial comparing CT and CCRT as an adjuvant therapy after surgery in T1/T2 patients, including those with pelvic lymph node metastases, is currently underway. However, our data suggest that performing CT alone after surgery in T2N1 patients is likely to worsen the prognosis.

Survival impact of adjuvant concurrent chemoradiotherapy after radical hysterectomy in FIGO stage IIIC1 cervical adenocarcinoma

BACKGROUND

We evaluated the survival effect of adjuvant concurrent chemoradiotherapy after radical hysterectomy in patients with clinical pelvic node-positive cervical adenocarcinoma.

METHODS

Patients with pelvic node-positive cervical adenocarcinoma diagnosed between 2000 and 2016 at our institution were identified. Survival was compared between patients who underwent radical hysterectomy alone and those who received concurrent chemoradiotherapy as an adjuvant treatment. Survival analysis using log-rank test and Cox proportional hazards model was performed.

RESULTS

We identified 80 patients who underwent radical hysterectomy for clinical pelvic node-positive cervical adenocarcinoma; of these, four with pathological pelvic node-negative adenocarcinoma were excluded. Of the 76 patients, 27 underwent radical hysterectomy alone and 49 received radical hysterectomy followed by concurrent chemoradiotherapy. With a median follow-up of 53 months, the 5-year overall survival rate was 51.0% in patients who underwent radical hysterectomy alone versus 53.0% in patients who received additional concurrent chemoradiotherapy (log-rank p = 0.455).

CONCLUSION

The addition of concurrent chemoradiotherapy after radical hysterectomy did not significantly improve survival among patients with pelvic node-positive cervical adenocarcinoma. More appropriate treatment strategies are needed to improve the survival outcomes of these patients.

A case of cervical adenocarcinoma arising from endometriosis in the absence of human papilloma virus infection

Endometriosis-related cervical neoplasms are rare, and their clinicopathological features and association with human papilloma virus infection are unclear. A postmenopausal woman with recently diagnosed cervical adenocarcinoma was referred to our hospital. After further investigation, we suspected a stage IIB neoplasm that originated from endometriosis of the cervix or left parametrium. A radical hysterectomy was performed, and pathological examination confirmed a stage IIB cervical endometrioid carcinoma arising from the endometriosis in the cervix to the left parametrium that invaded the cervix; human papilloma virus infection of tumor cells was not detected. Endometriosis-related neoplasms can occur in the cervix or parametrium and present as cervical cancer. The neoplasm described here was not associated with human papilloma virus infection.

Randomized study between radical surgery and radiotherapy for the treatment of stage IB-IIA cervical cancer: 20-year update

OBJECTIVE

Stage IB-IIA cervical carcinoma can be equally cured either by radical surgery or radiotherapy (RT). Albeit such policies show the same efficacy, they carry a different morbidity. This is an update after 20 years of a previously published randomized trial of RT vs. surgery in the treatment of stage IB-IIA cervical cancers to assess long-term survival and morbidity and the different pattern of relapse between the 2 modalities.

METHODS

Between September 1986 and December 1991, women referred for a newly diagnosed stage IB and IIA cervical carcinoma were randomized to radical surgery or RT. The primary outcome measures were long-term survival and complications rate. The secondary outcome was recurrence of the disease.

RESULTS

Three-hundred forty-three eligible women were randomized: 172 to radical surgery and 171 to external RT. Minimum follow-up was 19 years. Thirty-three patients (10%) died of intercurrent disease (31 cases) or fatal complications (2 cases). Twenty-year overall survival is 72% and 77% in the 2 treatment groups (p=0.280), respectively. As a whole, 94 recurrences (28%) were observed. Median time to relapse was 13.5 (surgery group) and 11.5 months (radiotherapy group) (p=0.100), respectively. Multivariate analysis confirms that risk factors for survival are histotype (p=0.020), tumor diameter (p=0.008), and lymph node status (p<0.001).

CONCLUSION

The results of the present study seem to suggest that there is no treatment of choice for early stage cervical carcinoma in terms of survival. Long term follow-up confirms that the best treatment for the individual patient should take into account clinical factors such as menopausal status, comorbidities, histological type, and tumor diameter.

Lack of any impact of histopathology type on prognosis in patients with early-stage adenocarcinoma and squamous cell carcinoma of the uterine cervix

BACKGROUND

The aim of this study was to evaluate the prognosis of patients with stage IA-IIB cervical carcinoma and to investigate a possible correlation of histology with prognosis.

MATERIALS AND METHODS

Two hundred fifty one patients with adenocarcinoma and squamous cell carcinoma (SCC) histology for FIGO (International Federation of Gynecology and Obstetrics) stage IA-IIB uterine cervical carcinomas at the Radiation Oncology Clinic of GH Okmeydani Training and Research Hospital between January 1996 and December 2006 were selected, analyzed retrospectively and evaluated in terms of general characteristics and survival. Disease-free survival (DFS) and overall survival (OS) was calculated using the Kaplan-Meier method and differences were compared with the log-rank test. Multivariate analysis using a Cox-proportional hazards model was used to adjust for prognostic factors and to estimate hazard ratio (HR) with 95% confidence interval (CI).

RESULTS

There was no differences between the two tumour types in age, stage, pelvic nodal metastasis, parametrial invasion, surgical margin status, DSI, LVSI, maximal tumor diameter, grade, and treatment modalities. 5-year OS and DFS were 73% and 77%, versus 64% and 69%, for SCC and adenocarcinoma, respectively (p> 0.05). Multivariate analysis revealed independent prognostic factors including pelvic nodal metastasis and resection margin status for OS (p=0.008, p=0.002, respectively).

CONCLUSIONS

Prognosis of FIGO stage IA-IIB cervical cancer patients was found to be the same for those with adenocarcinoma and SCC.
