Matched-case comparison for the role of surgery in FIGO stage Ib1-IIa squamous cell carcinoma of cervix and suspicious para-aortic lymph node metastasis

Can we triumph over locally advanced cervical cancer with colossal para-aortic lymph nodes? A case report

BACKGROUND

Para-aortic lymph nodes (PALNs) are common sites for the regional spread of cervical squamous cell carcinoma (SCC).

CASE SUMMARY

We report the case of a 36-year-old woman who presented with cervical SCC with multiple bulky PALNs, largest measured 4.5 cm × 5 cm × 10 cm. The patient was treated with radical intent with definitive chemoradiation using sequential dose-escalated adaptive radiotherapy, followed by maintenance chemotherapy. The patient achieved a complete response; she has been doing well since the completion of treatment with no evidence of the disease for 2 years.

CONCLUSION

Regardless of the size of PALN metastases of cervical carcinoma origin, it is still treatable (with radical intent) via concurrent chemoradiation. Adaptive radiotherapy allows dose escalation with minimal toxicity.

Risk Stratification Based on Metastatic Pelvic Lymph Node Status in Stage IIIC1p Cervical Cancer

Purpose

Stage IIIC1 cervical cancer showed heterogeneous in oncologic outcomes with highly variable survival rates. Our objective was to determine the prognostic significance of removed and metastatic pelvic lymph node status and further perform risk stratification in patients with stage IIIC1p cervical cancer.

Patients and Methods

Patients with stage IIIC1p cervical cancer and undergoing radical hysterectomy with lymphadenectomy in 2008–2018 were retrospectively analyzed. Patients’ stage was classified using the revised 2018 International Federation of Gynecology and Obstetrics (FIGO) staging schema. Univariate and multivariable models were used to examine the association between removed and metastatic lymph node status and recurrence-free survival/overall survival.

Results

During a median follow-up of 34 months, 73 relapses and 44 deaths were observed among 273 patients with stage IIIC1p cervical cancer. Parametrial involvement and metastatic lymph node ratio (mLNR) were identified as independent predictors for recurrence-free survival. Parametrial involvement and mLNR were independent predictors for overall survival. A stratification system was then created based on parametrial involvement and mLNR. A total of 123 (45.1%), 127 (46.5%) and 23 (8.4%) patients were classified into the low-risk, intermediate-risk, and high-risk groups, with as a 5-year recurrence-free survival of 81.7%, 51.1%, 38%, respectively. Compared to the low-risk group, the intermediate- and high-risk groups had a significantly greater risk of recurrence and death.

Conclusion

The prognosis of stage IIIC1p patients varied significantly. A risk stratification system based on parametrial involvement and mLNR successfully separated patients into low, intermediate, and high-risk group. Our findings could facilitate the practical use of further stratification in Stage IIIC1p cervical cancer.

Combining the negative lymph nodes count with the ratio of positive and removed lymph nodes can better predict the postoperative survival in cervical cancer patients

BACKGROUND

To evaluate the impacts of the negative lymph nodes (NLNs) count on the prognostic prediction of the ratio of positive and removed lymph nodes (RPL) in cervical cancer patients after radical hysterectomy and pelvic lymphadenectomy (RHPL).

METHODS

The positive and negative lymph node counts were calculated for 609 postoperative cervical cancer patients. The 5-year survival rate (5-YSR) was examined according to clinicopathologic variables. Cox regression was used to identify independent prognostic factors.

RESULTS

The NLNs count cutoffs were determined to be 10 and 25 with 5-YSR of 62.8% and 80.5%. The RPL of 13 patients who had the NLNs count of 10 or fewer was >20%. Among 242 patients who had 10 < NLNs count ≤ 25, 194 without positive nodes had the 5-YSR of 77.8%, 31 with 0% < RPL ≤ 5% had the 5-YSR of 3.2%, 15 with RPL > 20% had died when follow-up was completed. Among 354 patients who had NLNs count >25, 185 without positive nodes had the 5-YSR of 87.6%, 6 with 0% < RPL ≤ 5% had the 5-YSR of 25%, 15 with 5% < RPL ≤ 20% had the 5-YSR of 4.5%, and 2 with RPL >20% had died when follow-up was completed. Furthermore, stage, histologic grade and RPL were independently correlated with overall survival of cervical cancer patients after RHPL in the multivariate analysis.

CONCLUSIONS

RPL was an independent prognostic factor. The NLNs count is a key factor for improvement of survival prediction of RPL in cervical cancer.
