Recurrent cervical carcinoma after radical hysterectomy: an analysis of clinical aspects and prognosis

Utility of vaginal vault cytology in the local recurrence of cervical cancer

BACKGROUND

In Japan, 8000 women were newly diagnosed with cervical cancer in 2018. The healthcare insurance policy in Japan allows physicians to utilize vaginal volt cytology tests and serum biomarker measurement at every visit and imaging analysis at an adequate interval with screening for recurrence after initial treatment. However, the major surveillance guidelines published in the United States and European countries recommend focusing on pelvic examinations and symptom reviews to avoid unnecessary tests. This study aimed to reassess the benefits of standard surveillance methods adopted in this study by retrospective analysis.

METHODS

From January 2009 to December 2015, the medical records of patients with recurrence who were initially diagnosed with International Federation of Gynecology and Obstetrics stage I-III cervical cancer were collected for this study. Clinicopathological data were statistically analyzed to identify significant factors. In the first 2 years, the patients underwent regular surveillance, including pelvic examination, serum tumor marker tests, vaginal vault cytology every 1-3 months, and imaging analysis at 6- to 12-month intervals. In the following 2 years, the patients received a regular check with the same methods every 4 months and an annual imaging analysis. Afterward, the patients had regular screening every 6 to 12 months.

RESULTS

In the study period, 84 of the 981 patients experienced recurrence, and 88.1% had an asymptomatic recurrence. The disease-free interval was not related to the recurrence site. In univariate analysis, primary treatment, recurrence site, and diagnostic method were significant factors for survival outcomes. In contrast, multivariate analysis indicated that only primary treatment was a significant factor. In patients with local recurrence, multivariate analysis demonstrated that radiation as salvage therapy was an independent predictive factor for overall survival after recurrence.

CONCLUSIONS

In this retrospective study, routine imaging analysis and serum biomarker measurement did not contribute to patient prognosis after recurrence. In contrast, vaginal vault cytology can improve survival after recurrence in some patients. Tailored surveillance methods based on individual disease conditions and treatment modalities can improve post-recurrent survival outcomes.

The Clinical Aspects and Prognostic Factors Concerning Survival in Patients With Recurrent Cervical Cancer After Radical Hysterectomy and Adjuvant Chemoradiotherapy

Purpose

To investigate the recurrence patterns and prognostic factors of patients with recurrent cervical cancer after radical hysterectomy with node dissection (RHND) followed by adjuvant radiotherapy (RT)/concurrent chemoradiotherapy (CCRT).

Methods

The medical records of 153 patients with pre-operative International Federation of Gynecology and Obstetrics stage IB-IIA cervical cancer, who were treated with RHND followed by adjuvant RT/CCRT at the Liaoning Cancer Hospital between January 1, 2012 and May 31, 2018, were retrospectively analyzed.

Results

The median disease progression-free survival time was 16 months, and 75.2% (115/153) of patients had a relapse within two years. The survival of patients with multi-site relapse was significantly lower in comparison to those with relapse in a single site (p < 0.001). The survival rate of patients with distant metastasis (DM) and combined recurrence (DM with localregional recurrence [LR]) was significantly lower than that of patients with only LR (p = 0.006, p < 0.001). Furthermore, the survival rate of patients with combined recurrence was significantly lower than that of patients with only DM (p = 0.046). Multivariate analysis showed that resection margin involvement, para-aortic and common iliac lymph node metastasis, DM, no treatment after disease relapse, and early disease relapse were independent prognostic factors associated with poor survival.

Conclusion

Most of the cervical cancer patients who received initial RHND followed by adjuvant RT/CCRT had a relapse within two years. Resection margin involvement, para-aortic and common iliac lymph node metastasis, DM, no treatment after recurrence, and early disease relapse were found to be prognostic factors in patients with recurrent cervical cancer after RHND followed by adjuvant RT/CCRT.

Computed Tomography-Based Interstitial Brachytherapy for Recurrent Cervical Carcinoma in the Vaginal Apex

AIMS

To determine the factors influencing the outcomes of patients with recurrences post-hysterectomy for cervical cancers treated with external beam radiotherapy (EBRT) and interstitial brachytherapy.

MATERIALS AND METHODS

This prospective study accrued 90 patients between October 2008 and May 2014. All patients had had a prior hysterectomy and were diagnosed with recurrent vaginal apex cancers with squamous cell carcinomas. All underwent EBRT of 50 Gy (2 Gy/fraction) using tomotherapy-based image-guided intensity-modulated radiotherapy with concurrent chemotherapy of weekly cisplatin (40 mg/m²) followed by high dose rate interstitial brachytherapy boost of 20 Gy (4 Gy/fraction twice a day). Local relapse, disease-free and overall survival were determined.

RESULTS

At a median follow-up of 74 months (4-123 months), 10/90 (11%) patients had local failure as the first site of relapse and 12/90 (13.3%) had first distant relapse. Only one patient had synchronous local and distant relapse. The 7-year local relapse-free, disease-free and overall survival were 87.6, 68.3 and 68.3%, respectively. Grade 2 and 3 rectal toxicity were seen in 5.6 and 3.1% of patients, respectively. Among these, two (2.2%) patients underwent temporary diversion colostomy due to vaginal sigmoid and rectovaginal fistula. Grade 2 and 3 bladder toxicity were seen in 5.6 and 1.1% of patients, respectively. In summary, the lateral disease extent (P = 0.048) and the presence of nodal disease at diagnosis (P = 0.08) had a statistically significant or borderline impact on local relapse without any impact on disease-free survival. Tumour size in itself did not affect overall survival.

CONCLUSION

With the integration of EBRT and interstitial brachytherapy, most vaginal apex recurrences can be salvaged. An excellent local control and survival is achievable using intensity-modulated radiotherapy with image guidance and concurrent chemotherapy followed by high dose rate interstitial brachytherapy.

Molecular landscape of recurrent cervical cancer

Cervical cancer (CC) is a major gynecological problem in developing and underdeveloped countries. Despite the significant advancement in early detection and treatment modalities, several patients recur. Moreover, the molecular mechanisms responsible for CC recurrence remains obscure. The patients with CC recurrence often show poor prognosis and significantly high mortality rates. The clinical management of recurrent CC depends on treatment history, site, and extent of the recurrence. Owing to poor prognosis and limited treatment options, recurrent CC often presents a challenge to the clinicians. Several in vitro, in vivo, and patient studies have led to the identification of the critical molecular changes responsible for CC recurrence. Both aberrant genetic and epigenetic modifications leading to altered cell signaling pathways have been reported to impact CC recurrence. Researchers are currently trying to dissect the molecular pathways in CC and translate these findings for better management of disease. This article attempts to review the existing knowledge of disease relapse, accompanying challenges, and associated molecular players in CC.

Cervical cancer recurrence presenting as abdominal wall mass and accompanying cellulitis

Background

Most recurrences of early stage cervical cancer occur in the pelvis or lymphatic system. Distant metastases occur in a minority of patients. Large abdominal wall recurrence presenting as cellulitis and intra-abdominal mass is unusual and presents diagnostic as well as treatment challenges.

Case

A 46-year-old woman with a history of stage 1B1 poorly differentiated squamous cell carcinoma of the cervix 2 years earlier presented with infraumbilical abdominal wall erythema, tenderness and warmth to the touch. She had a subcutaneous mass in that area with associated abdominopelvic pain. Imaging showed a 9.5 × 11 cm lobulated mass in the anterior lower abdominal wall, encompassing the width of the lower rectus muscles also invading the small bowel and the bladder. Superimposed cellulitis led to the symptoms with which she presented. She was treated with intravenous antibiotics, and biopsy of the mass revealed squamous cell carcinoma consistent with her prior cervical cancer. She was treated with neoadjuvant chemotherapy followed by surgical debulking with negative margins and adjuvant chemotherapy. Three months after completing treatment she recurred in the inguinal lymph nodes and restarted multimodality treatment. She was without evidence of disease for the entire 18 months of follow up following treatment to the lymph nodes.

Conclusion

Cervical cancer recurrence patterns can be unique. Surveillance for recurrence may also include consideration of these unusual patterns of recurrence.

Selection criteria and colpotomic approach for safe minimally invasive radical hysterectomy in early-stage cervical cancer

OBJECTIVE

To evaluate oncologic outcomes of minimally invasive radical hysterectomy (RH) in early cervical cancer before and after the application of parametrial invasion (PMI) criterion on magnetic resonance imaging (MRI) and vaginal colpotomy (VC).

METHODS

A total of 216 International Federation of Gynecology and Obstetrics stage IB-IIA cervical cancer patients who underwent minimally invasive RH was identified between April 2006 and October 2018. Patients were classified into the pre-PMI intracorporeal or VC (IVC) (n=117) and post-PMI VC groups (n=99). In the pre-PMI IVC group, PMI criterion (intact stromal ring) on MRI was not applied and the patients received IVC. In the post-PMI VC group, surgical candidates were selected using the PMI criterion on MRI and all patients received VC only. Oncologic outcomes and prognostic factors associated with disease recurrence were analyzed.

RESULTS

The rate of positive vaginal cuff margins in the pre-PMI IVC group was higher than that in the post-PMI VC group (11.1% vs. 1.0%, p=0.003). Two-year disease-free survival was different between the 2 groups (84.5% in pre-PMI IVC vs. 98.0% in post-PMI VC groups, p=0.005). Disrupted stromal ring on MRI (hazard ratio [HR]=20.321; 95% confidence interval [CI]=4.903-84.218; p<0.001) and intracorporeal colpotomy (HR=3.059; 95% CI=1.176-7.958; p=0.022) were associated with recurrence.

CONCLUSION

The intact cervical stromal ring on MRI might identify the low-risk group of patients in terms of PMI and lymphovascular/stromal invasion in early cervical cancer. Minimally invasive RH should be performed in optimal candidates with an intact stromal ring on MRI, using VC.

Nerve-Sparing Radical Hysterectomy: A Pilot Study

Nerve-sparing radical hysterectomy has increasingly been used for cervical cancer, with less morbidity. We aimed with this study: i) to describe an alternative technique of nerve-sparing radical Piver III hysterectomy, using the CUSA®, in which attention was given to the uterosacral ligament and cardinal ligament; ii) to evaluate the feasibility of this new nerve-sparing technique; iii) to describe the surgical anatomy of the autonomic nervous system; iv) to assess the early incidence of bladder dysfunction. Twelve consecutive patients with local-regional advanced cervical cancer were enrolled in the study on nerve-sparing radical hysterectomy with extended pelvic lymphadenectomy. The mean age was 44 years (range, 30–59), mean body mass index was 24 kg/m2 (range, 18–30), mean operating time was 217 mins (range, 195–240), and mean blood loss was 437 cc (range, 200–750). The average hospitalization time was 9 days (range, 5–15 days). Two patients presented pathologically positive parametrium. Two of 12 (17%) patients were discharged with self-catheterism. In the first outpatient follow-up, 1 patient had recovered spontaneous voiding. The nerve-sparing technique with CUSA® can be an option to reduce radical hysterectomy-related morbidity. The technique proved to be feasible, with promising results in terms of preventing bladder dysfunction. An elevated body mass index and large tumors can impair the performance of the technique. Further studies clarifying neuroanatomy and neurophysiology of autonomic nervous structures, as well as a prospective controlled trial on nerve-sparing radical hysterectomy should be carried out to confirm our data.

Treatment results of adjuvant pelvic radiotherapy after radical hysterectomy for low-risk Stage IB1-IIA cervical cancer

Objective

The aim of the present retrospective analysis was to determine the effectiveness of pelvic radiotherapy (RT) as postoperative adjuvant therapy for low-risk cervical cancer.

Methods

Between June 2003 and April 2011, the clinical data of 225 International Federation of Gynecology and Obstetrics (FIGO) Stage IB1-IIA cervical cancer patients with low-risk factors were retrospectively reviewed, to analyze the relationship between adjuvant pelvic RT after radical hysterectomy and tumor recurrence or the patients' survival.

Results

The 5-year overall survival (OS) of 225 patients was 91.2% and 5-year disease-free survival (DFS) was 84.5%. The 5-year DFS and local regional disease-free survival was significantly better for patients in the RT group compared with that in the non-RT group (5-year DFS, 91.2% vs. 77.1%, P = 0.006; 5-year local regional disease-free survival 94.6% vs. 79.0%, P = 0.001). There were no statistically significant differences in the 5-year OS (92.9% vs. 89.4%, P = 0.371) and distant metastasis-free survival (96.4% vs. 96.5%, P = 0.887) between the two groups. Grade 3-4 treatment-related acute and late toxicities were not significantly different between the two groups. Subgroup analysis shows the 5-year DFS of RT alone, chemotherapy (CT) alone, non-RT/CT, RT and CT was, respectively, 90.5%, 62.9%, 81.4%, 92.5% separately (P = 0.002). The 5-year OS was not significantly different (91.6% vs. 78.2% vs. 92.9% vs. 96.9%, P = 0.887) between the four groups. Performing univariate analysis, postoperative CT was the only significant risk factor for DFS.

Conclusions

Our results indicate that postoperative adjuvant pelvic RT has a tendency to improve DFS especially local regional disease-free survival for FIGO Stage IB1-IIA cervical cancer patients with low-risk factors, without increased Grade 3-4 treatment-related acute and late toxicities, but non-standard CT is harmful to the prognosis (DFS) of these patients.

Is Routine Curettage a Useful Tool to Evaluate Persistent Tumor in Patients Who Underwent Primary Chemoradiation for Locally Advanced and/or Lymph Node Positive Cervical Cancer?

Objective

Response evaluation after primary chemoradiation (RCTX) in patients with cervical cancer remains difficult. Routine hysterectomy after primary RCTX is associated with considerable surgical morbidity without impact on survival. The purpose of the present study was to evaluate value of routine curettage after RCTX to detect persistent tumor.

Methods

Between 2006 and 2012, patients (n = 217) with cervical cancer in International Federation of Gynecology and Obstetrics stages IB1 N1 (14%), IB2 (9%), IIA (5%), IIB (46%), IIIA (4%), IIIB (15%), IVA (6%), and IVB (1%), respectively, underwent primary RCTX. After RCTX, curettage was recommended to all patients to evaluate response.

Results

In 136 (63%) of patients with cervical cancer, 1 or 2 consecutive curettages were performed at least 6 weeks after primary RCTX without any complications. In 21 (15%) patients, at least 1 curettage was positive for cervical cancer. In 7 patients, secondary hysterectomy was performed after 1 positive finding and persistent tumor was found in all of them. In the remaining 14 patients, there were 2 positive curettages in 5, 1 undetermined result followed by 1 positive in 3, and 1 positive followed by 1 negative in 6 patients, respectively. In the latter group, no tumor was detected in the uterus, whereas in all other patients with 2 curettages except one, residual carcinoma was detected. Five (24%) of 21 patients with positive histology are free of disease during follow-up. Decision for or against secondary hysterectomy was correct due to histological finding of curettage in 99%.

Conclusions

Routine curettage is a useful tool to guide decision for secondary hysterectomy with high accuracy after primary RCTX and avoids overtreatment.

Salvage radiotherapy with or without concurrent chemotherapy for pelvic recurrence after hysterectomy alone for early-stage uterine cervical cancer

PURPOSE

Treatment outcomes of patients with pelvic recurrence after hysterectomy alone for uterine cervical cancer who received salvage radiotherapy (RT) with or without concurrent chemotherapy were investigated.

METHODS

Salvage RT for recurrent cervical cancer confined to the pelvic cavity after hysterectomy alone was received by 33 patients. The median interval between initial hysterectomy and recurrence was 26 months. Whole-pelvic irradiation was delivered to median dose of 45 Gy, followed by a boost with a median dose of 16 Gy to the gross tumor volume. Cisplatin-based concurrent chemotherapy was administered to 29 patients.

RESULTS

The median follow-up period was 53 months for surviving patients. Most patients (97.0%) completed salvage RT of ≥45 Gy. Complete response (CR) was achieved in 23 patients (69.7%). Pelvic sidewall involvement and evaluation with positron-emission tomography-computed tomography were significantly associated with CR. The 5‑year progression-free survival (PFS), local control (LC), distant metastasis-free survival (DMFS), and overall survival (OS) rates were 62.7, 79.5, 72.5, and 60.1%, respectively. Initial International Federation of Gynecology and Obstetrics stage, pelvic sidewall involvement, and CR status were significant factors for PFS and OS rates in multivariate analysis. The incidence of severe acute and late toxicities (≥grade 3) was 12.1 and 3.0%, respectively.

CONCLUSION

Aggressive salvage RT with or without concurrent chemotherapy for recurrent cervical cancer confined to the pelvic cavity was feasible, with promising treatment outcomes and acceptable toxicities. However, even more intensive novel treatment strategies should be investigated for patients with unfavorable prognostic factors.

Practice patterns of adjuvant therapy for intermediate/high recurrence risk cervical cancer patients in Japan

Objective

Although radiation therapy (RT) and concurrent chemoradiotherapy (CCRT) are the global standards for adjuvant therapy treatment in cervical cancer, many Japanese institutions choose chemotherapy (CT) because of the low frequency of irreversible adverse events. In this study, we aimed to clarify the trends of adjuvant therapy for intermediate/high-risk cervical cancer after radical surgery in Japan.

Methods

A questionnaire survey was conducted by the Japanese Gynecologic Oncology Group to 186 authorized institutions active in the treatment of gynecologic cancer.

Results

Responses were obtained from 129 facilities. Adjuvant RT/CCRT and intensity-modulated RT were performed in 98 (76%) and 23 (18%) institutions, respectively. On the other hand, CT was chosen as an alternative in 93 institutions (72%). The most common regimen of CT, which was used in 66 institutions (51%), was a combination of cisplatin/carboplatin with paclitaxel. CT was considered an appropriate alternative option to RT/CCRT in patients with risk factors such as bulky tumors, lymph node metastasis, lymphovascular invasion, parametrial invasion, and stromal invasion. The risk of severe adverse events was considered to be lower for CT than for RT/CCRT in 109 institutions (84%).

Conclusion

This survey revealed a variety of policies regarding adjuvant therapy among institutions. A clinical study to assess the efficacy or non-inferiority of adjuvant CT is warranted.

Multimodality imaging of locally recurrent and metastatic cervical cancer: emphasis on histology, prognosis, and management

The management of recurrent and metastatic cervical cancer is evolving in concert with the available advanced imaging techniques and molecular targeted therapy. The purpose of this review is to provide an overview of imaging and treatment of cervical cancer patients with locoregional recurrence and metastatic disease, with emphasis on characteristic patterns of spread based on histology (squamous cell carcinoma and other subtypes), prognostic factors, diagnosis, and treatment response assessment, as well as updated therapeutic options.

Clinical Aspects and Prognostic Factors for Survival in Patients with Recurrent Cervical Cancer after Radical Hysterectomy

BACKGROUND

The aim of this study was to investigate the clinical aspects and prognostic factors for survival in patients with recurrent cervical cancer after radical hysterectomy with node dissection (RHND) for stages IA2-IB1.

PATIENTS AND METHODS

Clinicopathologic characteristics of the primary tumor, pattern of recurrence, method of detection, salvage treatment, and outcome were reviewed from the medical records of patients who underwent RHND between 1987 and 2015. Prognostic factors were identified using a Cox regression model.

RESULTS

Of 702 patients enrolled in the study, 84 (11.9%) had recurrence. 58, 17, and 9 patients had locoregional, distant, and combined recurrence, respectively. No association between clinicopathologic features and recurrence patterns was observed. Most recurrence patients (63.1%) complained of symptoms prior to examination. The majority of asymptomatic recurrence patients (71.4%) were diagnosed by physical and/or pelvic examination. 5-year overall survival after recurrence (SAR) was 34.3%. On multivariate analysis, pattern of recurrence (p = 0.003), symptom status (p = 0.011), age (p = 0.035), and white blood cell (WBC) count (p = 0.017) were independent prognostic factors for overall SAR.

CONCLUSION

Only pattern of recurrence, symptom status, age, and WBC count were found to be prognostic factors in recurrent cervical cancer after RHND. Follow-up programs after RHND should be directed toward early detection of recurrence.

Follow-up in Gynecological Malignancies: A State of Art

Objective

The main purpose of this article is to explore the current practice for follow-up of gynecological cancer, pointing out the different procedures, to determine the most clinically and cost-effective surveillance strategies after the primary treatment.

Materials and Methods

We analyzed the follow up strategies for ovarian, endometrial, and cervical cancer. All of the topics discussed below arose from the “ESGO State of Art Conference—Follow-up in gynaecological malignancies” in Turin, (September 11–13, 2014;http://torino2014.esgo.org/).

Results

Physical but these practices should be integrated with biomarkers or imaging strategies. Currently, most recommendations about follow-up are based on retrospective studies and expert opinion, and there is some disagreement on surveillance strategies due to lack of evidence-based knowledge.

Conclusions

All surveillance procedures should be evidence-based with a clearly defined purpose: there is a need for prospective studies to compare the effectiveness of different follow-up regimens measuring overall survival, detection of recurrence, quality of life (QoL), and costs as outcomes.

Addressing challenges in future surveillance after surgery for early-stage cervical cancer

OBJECTIVE

This study examines surveillance after early-stage cervical cancer surgery. Since the 1980s, the value of surveillance has been discussed continuously. The main question explored is whether surveillance serves the purpose of ensuring early diagnosis of recurrence.

MATERIALS AND METHODS

A retrospective cohort study included 389 women with cervical cancer who underwent surgery as the primary treatment modality at the Department of Obstetrics and Gynecology, Aarhus University Hospital, Denmark, from 1996 to 2011. We used data from patient files and the Danish National Pathology Data Bank. The cumulative risk was estimated by the Kaplan-Meier method and tested by the log-rank test.

RESULTS

Forty-three women (11%) had recurrence. Only 27% of the recurrent cases were diagnosed at a scheduled surveillance appointment, but they were often asymptomatic and seemed to have a better outcome after treatment compared with the recurrent cases diagnosed at self-referral.The 5-year survival was overall 91.3%, recurrence-free survival was 96%, and cancer-specific survival was 54%. The median recurrence-free interval was 23 months (range, 4-144) for the symptomatic patients and 14 months (range, 4-48) for the asymptomatic patients. The median survival after recurrence was 12 months (range, 2-132) for the symptomatic patients and 156 months (range, 40-180) for the asymptomatic patients.

CONCLUSIONS

At the moment, neither the value of surveillance nor the significance of self-referral related to survival after recurrence is known. In this study, those who are diagnosed with recurrence before symptom onset seem to fare better in terms of 5-year survival than those who are diagnosed after self-referral because of symptoms.

Salvage stereotactic body radiotherapy for locally recurrent uterine cervix cancer at the pelvic sidewall: Feasibility and complication

AIMS

To determine the feasibility of stereotactic body radiotherapy (SBRT) in patients with pelvic sidewall recurrence of uterine cervical cancer after radical hysterectomy or definitive radiotherapy.

METHODS

We retrospectively reviewed 23 patients with locally recurrent uterine cervical cancer limited to the pelvic sidewall who were treated with SBRT at our institution between January 2003 and May 2010. The SBRT dose ranged from 27 to 45 Gy (median, 39 Gy) in three fractions, and the fractional SBRT dose ranged from 9 to 15 Gy (median, 13 Gy).

RESULTS

The 2-year overall survival, local progression-free survival and disease progression-free survival rates were 43%, 65% and 52%, respectively. Patients with small tumors (gross tumor volume <30 cm(3) ) had a significantly longer 2-year overall survival rate and 2-year local progression-free survival rate than did patients with large tumors (overall survival rate: 89% vs 12%; P = 0.0001 and local progression-free survival: 85% vs 0%; P = 0.0199). There were three cases (13%) of severe toxicities (rectovaginal fistula). Pelvic pain relief was achieved in all patients. In particular, 10 of 14 patients (71%) achieved analgesic (nonsteroidal anti-inflammatory drug or narcotic) reduction of 50% or more from baseline.

CONCLUSION

SBRT is a feasible treatment option for women with pelvic sidewall tumors from recurrent uterine cervical cancer, especially for small recurrent tumors. However, SBRT should be used carefully in the treatment of large tumors, as the incidence of severe late toxicity increases with the size of the tumor.

Follow-up protocols for women with cervical cancer after primary treatment

BACKGROUND

Cervical cancer is the second most common cancer among women up to 65 years of age and is the most frequent cause of death from gynaecological cancers worldwide. Although surveillance of women after completion of primary treatment for cervical cancer is purported to have an impact on their overall survival (OS), no strictly defined follow-up protocols are available for these women. Wide diversity in management has been noted in the follow-up of women who have completed primary treatment for cervical cancer. Traditionally, women treated for cervical cancer undergo routine long-term, even life-long, follow-up. The primary objective of this practice has been to detect and treat recurrence early. This review sets out to systematically evaluate available evidence for the role of different models of follow-up after cervical cancer and the optimal use of investigations.

OBJECTIVES

To evaluate the benefits, harms and costs of different follow-up protocols for women who have completed primary treatment for cervical cancer.

SEARCH METHODS

We searched CENTRAL (The Cochrane Library 2013, Issue 1), the Cochrane Gynaecological Cancer Group (CGCG) Trials Register, MEDLINE and EMBASE up to January 2013. We also searched registers of clinical trials, abstracts of scientific meetings and reference lists of clinical guidelines and review articles and contacted experts in the field.

SELECTION CRITERIA

We searched for randomised controlled trials (RCTs) that compared different follow-up protocols after primary treatment in women with cervical cancer.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed whether potentially relevant studies met the inclusion criteria. No trials were found, and therefore no data were analysed.

MAIN RESULTS

The search strategy identified 1,377 unique references, of which all were excluded on the basis of title and abstract.

AUTHORS' CONCLUSIONS

We found no evidence to inform decisions about different follow-up protocols after primary treatment for women with cervical cancer. Ideally, a large RCT or, at the very least, well-designed non-randomised studies (NRSs) that use multi-variate analysis to adjust for baseline imbalances are needed to compare these follow-up protocols. Such studies could include prospective trials conducted to determine the benefits and harms of different follow-up protocols upon completion of primary treatment for cervical cancer, along with an RCT undertaken to compare predefined follow-up protocols versus participant-initiated follow-up versus no follow-up until a participant is referred to a gynaecological oncology service after signs or symptoms of recurrence have been identified in the primary care or community setting.

Post-treatment follow-up procedures in cervical cancer patients previously treated with radiotherapy

PURPOSE

We investigated the role of physical examination, CT scan, chest X-ray, and Pap smear in the routine follow-up program for cervical cancer patients previously treated with radiotherapy.

METHODS

The records of women who had developed recurrent cervical cancer after radiotherapy were retrospectively reviewed. The optimal procedure for the detection of recurrence was evaluated according to the disease-free interval (DFI). Survival analysis was performed based on the Kaplan-Meier method and comparisons between groups were made using the log-rank test.

RESULTS

A total of 146 recurrent cervical cancer patients were included in our database. The majority of recurrences were diagnosed either by symptoms, physical examination, or CT scan. The patients whose recurrent disease was detected by Pap smear, physical examination, or CT scan had a significantly longer survival than those detected by symptoms. When analyzed according to DFI, physical examination, and CT scan led to the detection of recurrence in patients with a DFI of 1-5 years. In contrast, chest X-ray and Pap smear only had a clinical impact on the diagnosis of recurrence in patients with a DFI of 1-2 years.

CONCLUSIONS

Chest X-ray and Pap smear can be routinely performed for the first 2 years after radiotherapy, but can be omitted or used sparingly thereafter.

Follow-up for women after treatment for cervical cancer

QUESTION

What is the most appropriate follow-up strategy for patients with cervical cancer who are clinically disease-free after receiving primary treatment?

PERSPECTIVES

For women with cervical cancer who have been treated with curative intent, follow-up includes identification of complications related to treatment and intervention in the event of recurrent disease. Most women who recur with cervical cancer are not curable; however, early identification of recurrence can alter disease management or treatment-planning options, and for those with a central pelvic recurrence and no evidence of distant disease, there is a potential for cure with additional therapy. Follow-up protocols in this population are variable, using a number of tests at a variety of intervals with questionable outcomes.

OUTCOMES

Outcomes of interest included recurrence, survival, and quality of life.

METHODOLOGY

The Gynecology Cancer Disease Site Group (DSG) conducted a systematic review of the literature and a narrative review of emerging clinical issues to inform the most appropriate follow-up strategy for patients with cervical cancer. The evidence was insufficient to specify a clinically useful recommended follow-up schedule, and therefore, the expert consensus opinion of the Gynecology Cancer DSG was used to develop recommendations on patient surveillance. The resulting recommendations were reviewed and approved by the Gynecology Cancer DSG and by the Program in Evidence-Based Care Report Approval Panel. An external review by Ontario practitioners completed the final phase of the review process. Feedback from all parties was incorporated to create the final practice guideline.

RESULTS

The systematic review of the literature identified seventeen retrospective studies. The Gynecology Cancer DSG used a consensus process to develop recommendations based on the available evidence from the systematic review, the narrative review, and the collective clinical experience and judgment of the DSG members.

PRACTICE GUIDELINE

The recommendations in this practice guideline are based on the expert consensus opinion of the Gynecology Cancer DSG, informed by evidence from retrospective studies. These are some general features of an appropriate follow-up strategy: 1. At a minimum, follow-up visits with a complete physical examination, including a pelvic-rectal exam and a patient history, should be conducted by a physician experienced in the surveillance of cancer patients. 2. There is little evidence to suggest that vaginal vault cytology adds significantly to the clinical exam in detecting early disease recurrence. 3. Routine use of various other radiologic or biologic follow-up investigations in asymptomatic patients is not advocated, because the role of those investigations has yet to be evaluated in a definitive manner. 4. A reasonable follow-up schedule involves follow-up visits every 3-4 months in the first 2 years and every 6-12 months in years 3-5. Patients should return to annual population-based general physical and pelvic examinations after 5 years of recurrence-free follow-up.

Posttreatment surveillance and diagnosis of recurrence in women with gynecologic malignancies: Society of Gynecologic Oncologists recommendations

Although gynecologic cancers account for only 10% of all new cancer cases in women, these cancers account for 20% of all female cancer survivors. Improvements in cancer care have resulted in almost 10 million cancer survivors, and this number is expected to grow. Therefore, determining the most cost-effective clinical surveillance for detection of recurrence is critical. Unfortunately, there has been a paucity of research in what are the most cost-effective strategies for surveillance once patients have achieved a complete response. Currently, most recommendations are based on retrospective studies and expert opinion. Taking a thorough history, performing a thorough examination, and educating cancer survivors about concerning symptoms is the most effective method for the detection of most gynecologic cancer recurrences. There is very little evidence that routine cytologic procedures or imaging improves the ability to detect gynecologic cancer recurrence at a stage that will impact cure or response rates to salvage therapy. This article will review the most recent data on surveillance for gynecologic cancer recurrence in women who have had a complete response to primary cancer therapy.

Follow-up routines in gynecological cancer - time for a change?

OBJECTIVE

To determine current practice of follow-up of Norwegian gynecological cancer patients, and to review available randomized controlled trials (RCTs) in gynecologic, breast and colorectal cancer patients in order to discuss whether such studies are feasible in gynecological cancer patients.

DESIGN

A combined questionnaire study and a systematic review of RCTs in follow-up of gynecological, breast, and colorectal cancers.

POPULATION

Gynecological, breast, and colorectal cancer patients.

METHODS

A questionnaire regarding follow-up routines was mailed to 31 gynecological departments in Norway. A systematic search on MEDLINE, EMBASE, and the Cochrane Library databases was conducted to identify RCTs in follow-up of breast, colorectal, and gynecological cancers.

RESULTS

The questionnaire study showed that the number of controls varied from eight to 16 during the first five years' post-treatment. Routine investigations such as chest X-ray and cytology were frequently used in endometrial and cervical cancer. All departments used CA-125 in follow-up of ovarian cancer patients. Reviewing the literature, 19 RCTs of varying methodological quality were identified for colorectal and breast cancers, and none for gynecologic cancer. Different follow-up models were compared, and most studies concluded that there were no significant differences in the detection of recurrence, overall survival, and quality of life between the studied groups.

CONCLUSIONS

Follow-up routines after gynecological cancer vary in Norway. The optimal approach is unknown and RCTs comparing follow-up protocols are missing. Studies of breast and colorectal cancer patients show that studies on follow-up strategies are feasible but sufficient sample size and observation time are important.

Prognostic factors for survival in patients with recurrent cervical cancer previously treated with radiotherapy

INTRODUCTION

The aim of this study was to identify the prognostic factors and to establish a model for the prediction of life expectancy in patients with recurrent cervical cancer that had previously been treated with radiotherapy.

METHODS

The records of consecutive women with recurrent cervical cancer after radiotherapy were retrospectively reviewed. Primary disease, follow-up, and recurrence data were collected. Univariate and multivariate analyses of prognostic factors of survival were performed.

RESULTS

A total of 162 patients were included in our database. The median survival after recurrence was 15 months. Multivariate analysis revealed that symptom status, the site of relapse, prior chemoradiotherapy, and treatment modality were significant prognostic factors in terms of survival after recurrence. Patient survival was inversely correlated with the number of these prognostic factors. When the patients were divided into 3 prognostic groups, (low risk: patients with no poor prognostic factors; intermediate: patients with one poor prognostic factor; and high-risk: patients with more than 2 poor prognostic factors), the patients in the high-risk group had a significantly shorter survival (median, 10 months) than those with one risk factor (median, 20 months) or no risk factors (median, 36 months).

CONCLUSIONS

Symptom status, the site of relapse, prior chemoradiotherapy, and treatment modality are significant prognostic factors in patients with recurrent cervical cancer that had previously been treated with radiotherapy. Our prognostic model, composed of 4 clinical variables, may enable physicians to predict survival more accurately.

Nerve-sparing radical hysterectomy: local recurrence rate, feasibility, and safety in cervical cancer patients stage IA to IIA

To clarify the debate about the possible threat of sparing the pelvic autonomic nerves in radical hysterectomy for cervical cancer to radicality, comparative studies of nerve-sparing and conventional surgery are necessary. The aim of his study was to analyze and compare local recurrence rate, feasibility, and safety of nerve-sparing and non-nerve-sparing radical hysterectomy.

METHODS

In a cohort study with 2 years of follow-up, 246 patients with cervical cancer of stages IA to IIA were analyzed: 124 in the non-nerve-sparing group (1994-1999) and 122 in the group where nerve-sparing was the intention-to-treat (2001-2005). Local recurrence rate, local recurrence-free survival, feasibility, and safety were analyzed and compared.

RESULTS

The clinical characteristics of the treatment groups were comparable. Sparing the nerves unilaterally or bilaterally was possible in 80% of cases of the nerve-sparing group. Local recurrence rates in the non-nerve-sparing (4.9%) and nerve-sparing (8.3%) group were not significantly different. Mean local recurrence-free survival within 2 years were 22.7 and 22.0 months, respectively. Univariate and multivariate regression analyses showed that nerve-sparing treatment was not a significant prognostic factor for local recurrence. With respect to perioperative and postoperative parameters, operating time and blood loss were less in the nerve-sparing group and mortality was equal (1 patient); the postoperative course of the nerve-sparing group was similar to the state-of-the-art of conventional radical hysterectomy.

CONCLUSIONS

On the basis of the results of our study, we consider the nerve-sparing technique for cervical cancer stages IA to IIA feasible and safe.

Pattern of failure and value of follow-up procedures in endometrial and cervical cancer patients

OBJECTIVE

The aim of this study was to evaluate the outcome benefit of follow-up protocols for patients with recurrent endometrial and cervical cancer.

METHODS

A retrospective review on patients primarily treated at the Division of Gynecologic Oncology, University of Brescia, was performed. We focused our attention on recurrent patients and we evaluated the pattern of relapse and the presence of symptoms or signs of disease at recurrence and evidence of disease on routine follow-up test or visits.

RESULTS

The vast majority of recurrences occurred within the first 3 years after primary treatment (78% and 87% in endometrial and cervical cancers, respectively). A better overall survival from relapse was observed when vaginal relapse was compared to other sites in endometrial cancer patients and when pelvic recurrence was compared to distant sites in cervical cancer cases. Recurrent endometrial and cervical cancer patients were symptomatic in 52% and 65% of cases, respectively. Among asymptomatic recurrent endometrial cancer cases, pelvic examination, abdominal or pelvic ultrasound and CT could detect 92% of relapses, while the vast majority of cervical cancer relapses could be diagnosed by pelvic examination and/or CT (85%).

CONCLUSION

Endometrial cancer patients showed a significantly better prognosis when the recurrence was detected during follow-up visits, thus supporting the real advantage of our surveillance programs, while no statistically significant differences were found in survival of cervical cancer patients between the symptomatic and the asymptomatic group.

Surgical treatment for neuroendocrine carcinoma of the uterine cervix

OBJECTIVE

To identify the best operative approach for neuroendocrine cervical carcinoma (NECC).

METHODS

The records of surgically treated patients with stages IB to IIB NECC were reviewed.

RESULTS

Of 10 patients who met the study criteria for NECC and underwent radical hysterectomy, 4 had pT1bN0, 4 had pT1bN1, 1 had pT2aN0, and 1 had pT2bN1 disease. Those with pT1bN1 or pT2bN1 disease received postoperative adjuvant radiotherapy and/or chemotherapy, and recurrence occurred in 7 patients (70%). Among these 7 patients, 5 (71%) had a primary NECC tumor with deep stromal invasion and 5 (71%) had extrauterine disease (parametrium and/or lymph node). The recurrences in 6 patients (86%) were located outside the pelvis (lung, liver, or brain). Stromal invasion was 6 mm or less in the 3 patients who did not experience disease recurrence.

CONCLUSIONS

Pelvic control by radical hysterectomy may not be beneficial for patients with NECC except for those with an early invasive lesion.

Quality of life in newly diagnosed cancer patients waiting for surgery is seriously impaired

BACKGROUND AND OBJECTIVES

Newly diagnosed cancer patients waiting for initial surgery experience a stressful time. Study objectives were (1) to examine the quality of life (QL) of these patients by comparing QL (a) between the four diagnostic groups included in this study, (b) to the QL of the general population, (2) to determine the factors that contribute most to patients' overall QL.

METHODS

One hundred ninety six patients with lung, periampullary, oesophageal and cervical cancer completed questionnaires on generic QL (SF-36), overall QL, cancer-site specific symptoms (EORTC-modules), anxiety (STAI), health expectations, demographics and comorbidity.

RESULTS

Between diagnostic groups no significant differences were found on generic QL. As compared to the general population, generic QL was impaired on all aspects except bodily pain. Using stepwise regression analysis, 46% of the variance in overall QL was explained with the SF-36 scales vitality (Beta = 0.43) and mental health (Beta = 0.23) being the most important predictors.

CONCLUSIONS

The QL of these patients is seriously impaired. In this stage, not cancer-site specific aspects but fatigue and emotions colour their lives. It is recommended to keep the waiting period brief. In addition, suggestions are offered by which physicians might help their patients in alleviating the distress.

Routine follow-up after treatment for a gynecological cancer: a survey of practice

The objective of this study was to determine current practice with regards to follow-up after gynecological malignancy. A questionnaire survey of all lead clinicians in gynecological cancer centers in England was done. The most common duration of routine follow-up was 5 years for all of the main gynecological cancers (ovarian, endometrial, vulval, and cervical). The most common follow-up patterns were three monthly for 2 years then six monthly for 3 years after ovarian cancer; three monthly for the first year, four monthly for the second year, six monthly for the third year then annually for 1 year after endometrial cancer; three monthly for the first year, four monthly for the second year, six monthly for the third and fourth years, then annually for 1 year after vulval cancer; three monthly for the first year, four monthly for the second year, six monthly for the third and fourth years, then annually for 1 year after cervical cancer. The test for CA125 was routinely performed by 67% of cancer networks to detect recurrence after ovarian cancer. Routine follow-up after gynecological cancer continues to be standard practice, despite limited evidence to support its use. Prospective research is needed to determine best practice.

Management of recurrent cervical cancer

Treatment for cervical cancer is very successful, especially in early stages. However, most patients presenting in late stages of disease will experience recurrence. The prognosis of recurrent disease is very poor and treatment options are limited. The diagnosis of recurrence may be apparent or difficult, but determining the extent of disease is always complex. Routine follow-up of asymptomatic patients has other objectives and is not a reliable way to detect recurrences. Symptomatic patients require extensive investigation to detect the extent of the disease. For patients with central pelvic recurrences, exenteration offers the prospect of survival in more than one-third of cases. Newer developments include laterally extended endopelvic resection that may become an option for patients with more extensive pelvic recurrence. For patients with recurrences of cervical cancer, the roles of second-time radiotherapy or postradiation chemotherapy are very limited. Palliative treatment is important for all patients with untreatable disease. Pain relief forms a central part of palliative care. Caregivers also experience emotional feelings and probably function best in a system offering strong colleageal support.

The role of routine follow-up after gynecological malignancy

The objective of this article was to determine the evidence base for routine follow-up after gynecological malignancy. Only articles with a survival analysis were included. Relevant articles were identified by a comprehensive literature search of the main biomedical databases, hand searching of references of selected articles, and expert spotting of relevant journals and proceedings of international meetings. A two-stage extraction of data was undertaken. No prospective trials were identified. Twenty-nine retrospective case series analyses and one poster presentation met the inclusion criteria. Eight articles and one letter on endometrial cancer, six articles and one poster presentation on cervical cancer, and two articles in vulval cancer were reviewed. Only one article in endometrial cancer showed any survival benefit from routine follow-up, but it was of very poor methodologic quality. Two articles found a survival benefit from routine follow-up after cervical cancer. The two articles on vulval cancer did not find any survival benefit from routine review. There is no prospective research on the benefits of routine follow-up after gynecological cancer. Retrospective evidence calls in to question the benefit of universal follow-up. Prospective research is urgently needed.

Clinical aspects and prognosis of pelvic recurrence of cervical carcinoma

OBJECTIVE

To identify which patients with locally recurrent cervical carcinoma are potentially curable.

METHOD

A total of 664 stage IB-IVA patients were examined following surgery or radiotherapy.

RESULT

Among the 664 patients, 193 (29%) developed recurrence. Sixty-seven (35%) of these recurrences were located in the pelvis alone. Among these 67 recurrences, 24 (35%) were central recurrences and the remaining 43 (65%) were pelvic side-wall recurrences. Of the 24 patients with central recurrences, 8 were salvaged. Of these 8 patients, 3 underwent pelvic exenteration, and 5 received optimal radiotherapy. The recurrent tumor in these 5 survivors who received radiotherapy had consisted of a small (<2 cm) tumor. All 43 patients with pelvic wall recurrence developed progressive disease.

CONCLUSION

The following patients are potentially curable: patients with a resectable, centrally located tumor who are candidates for pelvic exenteration, and patients with a small central recurrence for whom complete radiation therapy is feasible.

Do the pelvic lymph nodes predict the parametrial status in cervical cancer stages IB-IIA?

The aim of this study was to determine whether the pelvic lymph nodes would predict the parametrial status in patients with cervical cancer stages IB1-IIA submitted to radical surgery and pelvic lymphadenectomy. To this end, we evaluated the relationship between positive and negative pelvic lymph nodes and their parametria. Our final purpose was to use this information to recommend the tailoring of the parametrial resection according to the status of pelvic lymph nodes to decrease the morbidity related with radical paratrectomy. From January 1996 to December 2001, 107 consecutive patients with cervical cancer stages IB1 and IIA were primarily treated by radical hysterectomy type III with systematic pelvic lymphadenectomy in a prospective study. Parametria were studied in two sections: the first included the tissue adjacent to the cervix, and the second the distal 2/3. Lymph nodes were routinary processed. Twenty-two patients (20.6%) had positive pelvic nodes and 16 patients (14.9%) had parametrial involvement, mostly by direct extension. Eight patients with positive pelvic nodes (36.4%) had parametrial involvement, whereas among 85 patients with negative pelvic nodes only eight patients (9.4%) had parametrial involvement (P < 0.001), most in internal parametria (62.5%). The sensitivity of pelvic lymph nodes for parametrial involvement was 50% and the positive predictive value was 36.4%, whereas the specificity was 84.6%; and the negative predictive value 90.6%. In the group of negative pelvic lymph nodes, only two patients (2.3%) had parametrial involvement beyond internal parametria. The univariated and multivariated analysis of prognostic factors was always significant but without a significant independent factor for positive parametria. Pelvic lymph nodes appear as good predictors of parametrial status, especially in node-negative patients, and could be used to decrease the paratrectomy in radical surgery.

Value of routine follow-up procedures for patients with stage I/II cervical cancer treated with combined surgery–radiation therapy

BACKGROUND

The aim of this study was to determine the value of routine follow-up for the detection of recurrence in patients treated for cervical cancer.

PATIENTS AND METHODS

From 1986 to 1998, 583 women with stage I and II cervical carcinoma were treated with combined surgery-radiation therapy. After treatment, follow-up was based on clinical examination, a systematic Pap smear and radiography (chest X-ray and abdomino-pelvic ultrasonography).

RESULTS

Forty-five patients had recurrence observed with a delay > or = 6 months following the end of treatment. Thirty-eight patients had symptoms and seven were asymptomatic at the time of their recurrence. Among asymptomatic patients only two recurrences were diagnosed following routine examinations. Survival is similar in asymptomatic and symptomatic recurrent patients.

CONCLUSIONS

In conclusion, follow-up of patients treated for cervical cancer based on routine Pap smears and systematic radiography does not permit earlier detection of recurrence and does not increase survival.

Recurrent cervical cancer: detection and prognosis

BACKGROUND

Only a small proportion of cervical cancer recurrences is detected during routine follow-up. We investigated which percentage of recurrences is detected during follow-up, which diagnostic tools are helpful to detect recurrent disease and which factors are of prognostic significance once recurrent disease has been established in patients treated for cervical cancer stage IB-IVA.

METHODS

Characteristics of the primary tumor, characteristics of recurrent disease and follow-up were collected retrospectively from clinical records of 277 patients who achieved a complete remission of at least 3 months after primary treatment for cervical cancer in 1992, 1993 and 1994 in three university hospitals in the Netherlands.

RESULTS

Of 277 patients, 47 (17%) developed recurrent disease; this was most often detected after self-referral (45%), and in 32% during routine follow-up. Survival did not differ significantly between these two groups. The presence of symptoms (87%) was the most important first abnormal test result leading to diagnosis of recurrence. In univariate analysis, disease-free interval (DFI) and treatment modality were significant prognostic factors for crude survival of recurrence. However, treatment modality varied considerably and the subgroups were small. Therefore, multivariate analysis was not feasible and clinically valid conclusions could not be drawn.

CONCLUSIONS

In only 32% of all cases, recurrence was detected during a scheduled follow-up visit. In the majority of patients, recurrent cervical cancer was detected by symptoms (87%). In recurrent disease, DFI was a prognostic factor for survival.

Recurrent cervical carcinoma after primary radical surgery

OBJECTIVE

This study was undertaken to investigate prognostic factors in patients with recurrent cervical carcinoma who had undergone a primary radical hysterectomy and pelvic lymphadenectomy.

STUDY DESIGN

A retrospective analysis of 177 patients with recurrent cervical carcinoma after radical hysterectomy and pelvic lymphadenectomy for stage IB to II disease at a single institution was performed to evaluate clinicopathologic parameters, time to recurrence, pattern of failure, use of salvage therapy, and survival after recurrence.

RESULTS

The 5-year survival rate from diagnosis of recurrence in this series was 10.1%. Survival after recurrence was significantly decreased in patients with pelvic lymph node metastasis at primary surgery and adenocarcinoma-adenosquamous carcinoma histologic type. Patients with extravaginal recurrences receiving chemoradiation for recurrent cervical carcinoma had significantly better outcomes than those receiving radiation alone. Six patients who had a distant relapse at a sole site had prolonged survival after salvage therapy, which was accomplished by chemoradiation, surgery plus radiotherapy, or surgery alone.

CONCLUSIONS

Our results demonstrate the benefit of adding chemotherapy to radiotherapy in the treatment of recurrent cervical carcinoma. Salvage multimodality treatment should be offered to selected patients who have isolated relapse at a single distant site.
