Cervical conization and the risk of preterm delivery.
Am J Obstet Gynecol. 2011 Jul;205(1):19-27. doi: 10.1016/j.ajog.2011.01.003. Epub 2011 Feb 23.
Abstract/Text
The current body of literature concerning cervical conization and its effect on subsequent pregnancy outcome is conflicting. Depending on the type of conization procedure that is examined and the quality of the control group, the results and conclusions vary widely. Because treatment for cervical intraepithelial neoplasia is commonplace among women of reproductive age, it is imperative that practitioners have an understanding of the issues surrounding the treatment. Therefore, this review will summarize the published literature that addresses excisional procedures of the uterine cervix and the risk of preterm delivery in subsequent pregnancies and provide reasonable treatment recommendations for women with cervical abnormalities and a desire for future fertility.

Randomised study of radical surgery versus radiotherapy for stage Ib-IIa cervical cancer.
Lancet. 1997 Aug 23;350(9077):535-40. doi: 10.1016/S0140-6736(97)02250-2.
Abstract/Text
BACKGROUND: Stage Ib and IIa cervical carcinoma can be cured by radical surgery or radiotherapy. These two procedures are equally effective, but differ in associated morbidity and type of complications. In this prospective randomised trial of radiotherapy versus surgery, our aim was to assess the 5-year survival and the rate and pattern of complications and recurrences associated with each treatment.
METHODS: Between September, 1986, and December, 1991, 469 women with newly diagnosed stage Ib and IIa cervical carcinoma were referred to our institute. 343 eligible patients were randomised: 172 to surgery and 171 to radical radiotherapy. Adjuvant radiotherapy was delivered after surgery for women with surgical stage pT2b or greater, less than 3 mm of safe cervical stroma, cut-through, or positive nodes. The primary outcome measures were 5-year survival and the rate of complications. The analysis of survival and recurrence was by intention to treat and analysis of complications was by treatment delivered.
FINDINGS: 170 patients in the surgery group and 167 in the radiotherapy group were included in the intention-to-treat analysis; scheduled treatment was delivered to 169 and 158 women, respectively, 62 of 114 women with cervical diameters of 4 cm or smaller and 46 of 55 with diameters larger than 4 cm received adjuvant therapy. After a median follow-up of 87 (range 57-120) months, 5-year overall and disease-free survival were identical in the surgery and radiotherapy groups (83% and 74%, respectively, for both groups), 86 women developed recurrent disease: 42 (25%) in the surgery group and 44 (26%) in the radiotherapy group. Significant factors for survival in univariate and multivariate analyses were: cervical diameter, positive lymphangiography, and adeno-carcinomatous histotype. 48 (28%) surgery-group patients had severe morbidity compared with 19 (12%) radiotherapy-group patients (p = 0.0004).
INTERPRETATION: There is no treatment of choice for early-stage cervical carcinoma in terms of overall or disease-free survival. The combination of surgery and radiotherapy has the worst morbidity, especially urological complications. The optimum therapy for each patient should take account of clinical factors such as menopausal status, age, medical illness, histological type, and cervical diameter to yield the best cure with minimum complications.

Sustained efficacy and immunogenicity of the human papillomavirus (HPV)-16/18 AS04-adjuvanted vaccine: analysis of a randomised placebo-controlled trial up to 6.4 years.
Lancet. 2009 Dec 12;374(9706):1975-85. doi: 10.1016/S0140-6736(09)61567-1.
Abstract/Text
BACKGROUND: Prophylactic human papillomavirus (HPV) vaccines have to provide sustained protection. We assessed efficacy, immunogenicity, and safety of the HPV-16/18 AS04-adjuvanted vaccine up to 6.4 years.
METHODS: Women aged 15-25 years, with normal cervical cytology, who were HPV-16/18 seronegative and oncogenic HPV DNA-negative (14 types) at screening participated in a double-blind, randomised, placebo-controlled initial study (n=1113; 560 vaccine group vs 553 placebo group) and follow-up study (n=776; 393 vs 383). 27 sites in three countries participated in the follow-up study. Cervical samples were tested every 6 months for HPV DNA. Management of abnormal cytologies was prespecified, and HPV-16/18 antibody titres were assessed. The primary objective was to assess long-term vaccine efficacy in the prevention of incident cervical infection with HPV 16 or HPV 18, or both. We report the analyses up to 6.4 years of this follow-up study and combined with the initial study. For the primary endpoint, the efficacy analysis was done in the according-to-protocol (ATP) cohort; the analysis of cervical intraepithelial neoplasia grade 2 and above (CIN2+) was done in the total vaccinated cohort (TVC). The study is registered with ClinicalTrials.gov, number NCT00120848.
FINDINGS: For the combined analysis of the initial and follow-up studies, the ATP efficacy cohort included 465 women in the vaccine group and 454 in the placebo group; the TVC included 560 women in the vaccine group and 553 in the placebo group. Vaccine efficacy against incident infection with HPV 16/18 was 95.3% (95% CI 87.4-98.7) and against 12-month persistent infection was 100% (81.8-100). Vaccine efficacy against CIN2+ was 100% (51.3-100) for lesions associated with HPV-16/18 and 71.9% (20.6-91.9) for lesions independent of HPV DNA. Antibody concentrations by ELISA remained 12-fold or more higher than after natural infection (both antigens). Safety outcomes were similar between groups: during the follow-up study, 30 (8%) participants reported a serious adverse event in the vaccine group versus 37 (10%) in the placebo group. None was judged related or possibly related to vaccination, and no deaths occurred.
INTERPRETATION: Our findings show excellent long-term efficacy, high and sustained immunogenicity, and favourable safety of the HPV-16/18 AS04-adjuvanted vaccine up to 6.4 years.

Concurrent chemotherapy and pelvic radiation therapy compared with pelvic radiation therapy alone as adjuvant therapy after radical surgery in high-risk early-stage cancer of the cervix.
J Clin Oncol. 2000 Apr;18(8):1606-13.
Abstract/Text
PURPOSE: To determine whether the addition of cisplatin-based chemotherapy (CT) to pelvic radiation therapy (RT) will improve the survival of early-stage, high-risk patients with cervical carcinoma.
PATIENTS AND METHODS: Patients with clinical stage IA(2), IB, and IIA carcinoma of the cervix, initially treated with radical hysterectomy and pelvic lymphadenectomy, and who had positive pelvic lymph nodes and/or positive margins and/or microscopic involvement of the parametrium were eligible for this study. Patients were randomized to receive RT or RT + CT. Patients in each group received 49.3 GY RT in 29 fractions to a standard pelvic field. Chemotherapy consisted of bolus cisplatin 70 mg/m(2) and a 96-hour infusion of fluorouracil 1,000 mg/m(2)/d every 3 weeks for four cycles, with the first and second cycles given concurrent to RT.
RESULTS: Between 1991 and 1996, 268 patients were entered onto the study. Two hundred forty-three patients were assessable (127 RT + CT patients and 116 RT patients). Progression-free and overall survival are significantly improved in the patients receiving CT. The hazard ratios for progression-free survival and overall survival in the RT only arm versus the RT + CT arm are 2.01 (P =.003) and 1.96 (P =. 007), respectively. The projected progression-free survivals at 4 years is 63% with RT and 80% with RT + CT. The projected overall survival rate at 4 years is 71% with RT and 81% with RT + CT. Grades 3 and 4 hematologic and gastrointestinal toxicity were more frequent in the RT + CT group.
CONCLUSION: The addition of concurrent cisplatin-based CT to RT significantly improves progression-free and overall survival for high-risk, early-stage patients who undergo radical hysterectomy and pelvic lymphadenectomy for carcinoma of the cervix.

A randomized trial of pelvic radiation therapy versus no further therapy in selected patients with stage IB carcinoma of the cervix after radical hysterectomy and pelvic lymphadenectomy: A Gynecologic Oncology Group Study.
Gynecol Oncol. 1999 May;73(2):177-83. doi: 10.1006/gyno.1999.5387.
Abstract/Text
OBJECTIVE: The objective of this study was to evaluate the benefits and risk of adjuvant pelvic radiotherapy aimed at reducing recurrence in women with Stage IB cervical cancer treated by radical hysterectomy and pelvic lymphadenectomy.
METHODS: Two hundred seventy-seven eligible patients were entered with at least two of the following risk factors: >1/3 stromal invasion, capillary lymphatic space involvement, and large clinical tumor diameter. Of 277 patients, 137 were randomized to pelvic radiotherapy (RT) and 140 to no further treatment (NFT).
RESULTS: Twenty-one (15%) in the RT group and 39 (28%) in the NFT group had a cancer recurrence, 18 of whom were vaginal/pelvic in the RT and 27 in the NFT group. In the RT group, of 18 (13%) who died, 15 died of cancer. In the NFT group, of the 30 (21%) who died, 25 died from cancer. Life table analysis indicated a statistically significant (47%) reduction in risk of recurrence (relative risk = 0.53, P = 0.008, one-tail) among the RT group, with recurrence-free rates at 2 years of 88% versus 79% for the RT and NFT groups, respectively. Severe or life-threatening (Gynecologic Oncology Group grade 3 or 4) urologic adverse effects occurred in 4 (3.1%) in the RT group and 2 (1.4%) in the NFT group; 3 (2.3%) and 1 (0.7%) hematologic; 4 (3.1%) and 0 gastrointestinal (GI); and 1 (0.8%) and 0 neurologic, respectively. One patient's death was attributable to grade 4 GI adverse effects.
CONCLUSIONS: Adjuvant pelvic radiotherapy following radical surgery reduces the number of recurrences in women with Stage IB cervical cancer at the cost of 6% grade 3/4 adverse events versus 2.1% in the NFT group.

Comparison of adjuvant therapy for node-positive clinical stage IB-IIB cervical cancer: Systemic chemotherapy versus pelvic irradiation.
Int J Cancer. 2017 Sep 1;141(5):1042-1051. doi: 10.1002/ijc.30793. Epub 2017 Jun 8.
Abstract/Text
This was a nation-wide retrospective study in Japan examining women who underwent radical hysterectomy for clinical stage IB-IIB cervical cancer with pelvic and/or para-aortic lymph node metastasis between 2004 and 2008. Time to recurrence or death and patterns of disease recurrence were compared based upon the adjuvant treatment pattern: whole pelvic radiotherapy alone (n = 253), concurrent chemoradiotherapy (CCRT, n = 502) and chemotherapy alone (n = 319). Women who received chemotherapy alone had similar recurrence (5-year rates, 36.6% vs. 34.1%, adjusted-hazard ratio [HR] 0.95, 95% confidence interval [CI] 0.70-1.28, P = 0.72) and cervical cancer mortality (24.7% vs. 21.8%, adjusted-HR 0.96, 95% CI 0.67-1.38, P = 0.83) rates compared to those who received CCRT on multivariate analysis. However, when recurrence patterns were stratified, chemotherapy treatment was independently associated with decreased risk of distant recurrence (5-year cumulative rates, 19.2% vs. 24.6%, adjusted-HR 0.47, 95% CI 0.31-0.71, P < 0.001) but increased risk of local recurrence (23.9% vs. 14.3%, adjusted-HR 2.03, 95% CI 1.34-3.08, P = 0.001) compared to CCRT. Non-squamous histology, parametrial involvement and high lymph node ratio were independent predictors for local recurrence, and presence of multiple risk factors was associated with high 5-year cumulative local recurrence rate in the chemotherapy group: no risk factor 3.9%, single factor 14.2-22.1%, and multiple risk factors 27.8-71.9% (P < 0.001). In conclusion, while exhibiting different recurrence patterns, systemic chemotherapy may be as effective a postoperative treatment as radiation-based therapy in node-positive high-risk stage IB-IIB cervical cancer. When tumor exhibits certain risk factors, chemotherapy alone is likely insufficient for local control and adding pelvic irradiation to systemic chemotherapy is recommended in this subgroup.

Posttherapy surveillance of women with cervical cancer: an outcomes analysis.
Gynecol Oncol. 2000 Aug;78(2):187-93. doi: 10.1006/gyno.2000.5860.
Abstract/Text
OBJECTIVE: The aim of this study was to develop a surveillance program that optimizes clinical outcome following primary treatment of women with cervical cancer.
METHODS: The records of 1096 patients with FIGO stage IB cervical cancer treated from 1983 to 1993 were retrospectively reviewed. Recurrence was analyzed by site, presence or absence of symptoms, method of detection, and survival. Univariate and multivariate analyses using a Cox proportional hazards model were performed.
RESULTS: One hundred thirty-three patients (13%) developed recurrent disease. Of these, 114 were symptomatic and 19 were asymptomatic at the time of recurrence. Thirty-seven patients recurred in the central pelvis, 21 each in the lung or pelvic wall, 22 in nodes, and 35 in other sites. The median disease-free interval was 17 months for symptomatic patients and 16 months for asymptomatic patients. The median survival from initial diagnosis was 31 months for symptomatic and 83 months for asymptomatic patients (P = 0.001). The median survival from recurrence was 11 months for symptomatic and 42 months for asymptomatic patients (P < 0.001). Multivariate analysis revealed that symptom status at time of recurrence was a significant predictor of survival, even when known prognostic factors were considered (P < 0.001). All asymptomatic pelvic recurrences were diagnosed by pelvic exam; all asymptomatic pulmonary recurrences were detected by chest radiographs. Pap smears did not detect a single asymptomatic recurrence.
CONCLUSIONS: Posttherapy surveillance programs are directed toward asymptomatic patients in whom early detection of recurrence may impact survival. These data indicate that a subset of women may benefit from surveillance. A model for surveillance is proposed.

Squamous cell carcinoma antigen: clinical utility in squamous cell carcinoma of the uterine cervix.
Gynecol Oncol. 1994 Nov;55(2):169-73. doi: 10.1006/gyno.1994.1272.
Abstract/Text
This study further defines the clinical utility of squamous cell carcinoma antigen (SCC-Ag) in initial squamous carcinoma of the cervix, response to treatment, and in the detection of recurrence. Serum specimens were drawn and analyzed from patients with squamous cell carcinoma. Charts were reviewed on 272 patients with 1053 samples evaluated. Treatment of patients prior to the availability of the assay and patients lost to follow-up resulted in lower total numbers of initial and recurrent values. Data were analyzed to detect trends during and after treatment. All values at or above the lowest detectable level of antigen were included; that is, 1.5 ng/ml and above. A SCC-Ag value > or = 2.0 ng/ml drawn at any time during the disease process has a 96.3% positive predictive value, while a value < 2.0 ng/ml is 97.2% specific for absence of disease. Fifty-three percent of 103 patients had elevated SCC-Ag levels prior to treatment, with the proportion increasing accordingly with advancing stage at diagnosis. In 70 patients with recurrence, 81% had elevated values. Squamous cell carcinoma antigen predicted recurrence an average of 6.9 months prior to detection of clinically evident disease. Patients with initially negative SCC-Ag levels may demonstrate elevated values with tumor recurrence. This marker accurately reflects the response to treatment in patients who have elevated levels prior to treatment. Squamous cell carcinoma antigen is a useful tumor marker in the management of patients with squamous cell carcinoma of the uterine cervix.

Clinical value of routine serum squamous cell carcinoma antigen in follow-up of patients with early-stage cervical cancer.
J Clin Oncol. 2001 Oct 1;19(19):3960-6.
Abstract/Text
PURPOSE: To investigate the contribution to recurrence detection and survival of serum squamous cell carcinoma antigen (SCC-ag) analysis in the follow-up of early-stage cervical cancer patients.
PATIENTS AND METHODS: Follow-up data were evaluated in patients with early-stage squamous cell cervical cancer treated by radical hysterectomy and pelvic lymphadenectomy with or without radiotherapy. Routine serum SCC-ag determination was performed at each follow-up visit.
RESULTS: Recurrent disease occurred in 35 (16%) of 225 patients and was preceded or accompanied by serum SCC-ag elevation 26 times (sensitivity, 74%). In five (14%) of these 35 patients, elevated serum SCC-ag was the first measured clinical indicator. Desite salvage therapy, all five patients died of disease. In the other 31 patients (21 with serum SCC-ag elevation), either symptoms and/or positive signs led to recurrence detection. Median survival time after recurrence was worse (9 months; range, 2 to 112+) for patients with an elevated serum SCC-ag value at recurrence in comparison with patients with normal serum SCC-ag values (20 months; range, 4 to 96; P <.01). In 23 of the 190 patients without recurrences, serum SCC-ag values became falsely elevated. In 16 of these 23 patients, the repeat sample after 6 weeks showed a normal SCC-ag, and in seven patients benign (especially skin) disorders were found.
CONCLUSION: Serum SCC-ag analysis results in earlier recurrence detection in a small proportion (14%) of patients but did not contribute to better survival. As long as treatment possibilities for recurrent cervical cancer patients are not improved, serum SCC-ag analysis should not be carried out in routine follow-up.
