Role of Tumor Mutation Burden Analysis in Detecting Lynch Syndrome in Precision Medicine: Analysis of 2,501 Japanese Cancer Patients. Cancer Epidemiol Biomarkers Prev 2020; 30:166-174. [PMID: 33046448 DOI: 10.1158/1055-9965.epi-20-0694] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2020] [Revised: 07/23/2020] [Accepted: 09/30/2020] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND Tumor mutation burden (TMB) is the total exonic mutation count per megabase of tumor DNA. Recent advances in precision medicine occasionally detect Lynch syndrome (LS) by germline sequencing for mismatch-repair (g.MMR) genes but not using TMB. The current study analyzes the utility of TMB in detecting LS. METHODS Whole-exome sequencing (ion-semiconductor sequencing) was performed for somatic and germline DNA from 2,501 various cancer patients to detect TMB and g.MMR sequencing. MMR IHC was conducted when high TMB (≥10) was detected in LS-related cancers with an additional condition of wild-type BRAF in colorectal cancers. Target sequencing and multiplex ligation-dependent probe amplification (MLPA) were further performed for g.MMR genes in MMR-deficient cancers (TMB-based g.MMR target sequencing). We compared universal sequencing and TMB-based target sequencing in their sensitivity for detecting LS. RESULTS LS was detected in 16 (0.6%) of the 2,501 patients: 1.1% (9/826) of colorectal cancer patients, 16.2% (6/37) of endometrial cancer patients, and 14.3% (1/7) of small intestine cancer patients. TMB-based g.MMR target sequencing (81.3%) showed superior sensitivity for detecting LS than universal g.MMR sequencing (56.3%; P = 0.127) but missed 3 LS patients (1 with a low-TMB cancer, 1 with a BRAF-mutant colorectal cancer, and 1 with an MMR-proficient cancer). Ion-semiconductor sequencing could detect single-nucleotide substitutions but not large deletions. POL-mutated cancers showed extremely high TMBs (48.4-749.2). CONCLUSIONS g.MMR target sequencing, combined with TMB, somatic BRAF mutation, and MMR IHC is an effective strategy for detecting LS. IMPACT TMB can be a biomarker for detecting LS in precision medicine.

Abstract
e18077 Background: Tissue factor pathway inhibitor 2 (TFPI2) is a novel serum biomarker that discriminates ovarian clear cell carcinomas (CCC) from borderline ovarian tumors (BD) and non-CCC epithelial ovarian cancers (EOC). We examined the prediction performances of TFPI2, including high specificity, for preoperative diagnosis of CCC in multi-center settings. Methods: We collected serum samples obtained preoperatively from patients with ovarian masses who needed surgical treatment to confirm pathological diagnoses in five hospitals in Japan. The diagnostic powers of serum levels of TFPI2 (cutoff value 270 pg/mL) and CA125 (cutoff value 35 U/mL) to discriminate CCC from BD, non-CCC-EOC, and benign lesions were compared. Results: A total of 351 patients (77 ovarian benign lesions, 65 BD and 209 EOC including 69 CCC) were analyzed. Serum TFPI2 levels were significantly higher in CCC patients (mean±SD, 508.2±812.0 pg/mL) than in patients with benign lesions (154.7±46.5), BD (181±95.5) and non-CCC EOC (265.4±289.1). TFPI2 had a high diagnostic specificity to CCC (sensitivity and specificity: 43.5% and 79.5%, respectively). The sensitivity of TFPI2 was improved to 71.1% when combined with CA125, and it was increased in Stage II–IV CCC (66.7%) compared with Stage I CCC (33.3%). In patients with benign endometriotic cysts (BEM), no patient was positive for TFPI2 but 71.4% (15/21) were CA125 positive. TFPI2 showed good performance in discriminating Stage II–IV CCC from BD and non-CCC EOC patients (AUC 0.815 for TFPI2 versus 0.505 for CA125) or from BEM (AUC 0.957 for TFPI2 versus 0.748 for CA125). Conclusions: High specificity of TFPI2 for the preoperative detection of CCC was re-verified with the defined cutoff level of TFPI2 in practice. TFPI2 and CA125 may have a substantial contribution to the precise prediction of intractable CCC. [Table: see text]

Abstract
A 62-year-old Japanese woman developed numbness of the extremities and megaloblastic anemia. She had undergone total abdominal hysterectomy, whole-pelvis radiation therapy and chemotherapy for gynecological cancer 10 years before. Chronic abdominal pain, diarrhea and intermittent small-bowel obstruction had afflicted her for a long time. We diagnosed her with vitamin B12 deficiency anemia and polyneuropathy due to chronic radiation enteritis causing malabsorption. Vitamin B12 injections improved her numbness and anemia. The early diagnosis and treatment of deficiency of vitamin B12 are important. Physicians should regularly measure vitamin B12 levels and supplement vitamin B12 as needed in patients with chronic radiation enteritis.

Abstract
This study aimed to establish the Japanese Cancer Genome Atlas (JCGA) using data from fresh frozen tumor tissues obtained from 5143 Japanese cancer patients, including those with colorectal cancer (31.6%), lung cancer (16.5%), gastric cancer (10.8%) and other cancers (41.1%). The results are part of a single-center study called "High-tech Omics-based Patient Evaluation" or "Project HOPE" conducted at the Shizuoka Cancer Center, Japan. All DNA samples and most RNA samples were analyzed using whole-exome sequencing, cancer gene panel sequencing, fusion gene panel sequencing and microarray gene expression profiling, and the results were annotated using an analysis pipeline termed "Shizuoka Multi-omics Analysis Protocol" developed in-house. Somatic driver alterations were identified in 72.2% of samples in 362 genes (average, 2.3 driver events per sample). Actionable information on drugs that is applicable in the current clinical setting was associated with 11.3% of samples. When including those drugs that are used for investigative purposes, actionable information was assigned to 55.0% of samples. Germline analysis revealed pathogenic mutations in hereditary cancer genes in 9.2% of samples, among which 12.2% were confirmed as pathogenic mutations by confirmatory test. Pathogenic mutations associated with non-cancerous hereditary diseases were detected in 0.4% of samples. Tumor mutation burden (TMB) analysis revealed 5.4% of samples as having the hypermutator phenotype (TMB ≥ 20). Clonal hematopoiesis was observed in 8.4% of samples. Thus, the JCGA dataset and the analytical procedures constitute a fundamental resource for genomic medicine for Japanese cancer patients.

Abstract
Background Somatic PTEN mutation occurs in a proportion of ovarian endometrioid carcinomas. However, these cancers have seldom been reported in diseases associated with germline PTEN variants, such as Cowden syndrome (CS). Case presentation The present case was a 39-year-old woman with a left ovarian carcinoma who demonstrated a germline splice variant of PTEN (c.1026 + 1G > T) following genome-wide whole exome sequencing of her germline DNA. Histology of her resected tumor revealed endometrioid carcinoma of the same type as a right ovarian cancer resected eight years previously. These tumors showed null immunostaining for PTEN. She was genetically diagnosed with CS. Despite her clinical examinations had demonstrated several characteristic findings of CS, including mammary fibroma, esophageal and skin papilloma, colonic hamartoma, uterine myoma, and lipoma, the clinicians could not approach this diagnosis. Conclusion Ovarian endometrioid carcinoma is generally thought to develop from endometrial tissue menstruated from the uterus and implanted on the ovary. To date, ovarian cancers have not been listed as CS-related cancers; however, ovarian endometrioid cancer can have a potential association with CS in endometriosis cases.

Abstract
Objective We aimed to propose a set of quality indicators (QIs) based on the clinical guidelines for cervical cancer treatment published by The Japan Society of Gynecologic Oncology, and to assess adherence to standard-of-care as an index of the quality of care for cervical cancer in Japan. Methods A panel of clinical experts devised the QIs using a modified Delphi method. Adherence to each QI was evaluated using data from a hospital-based cancer registry of patients diagnosed in 2013, and linked with insurance claims data, between October 1, 2012, and December 31, 2014. All patients who received first-line treatment at the participating facility were included. The QI scores were communicated to participating hospitals, and additional data about the reasons for non-adherence were collected. Results In total, 297 hospitals participated, and the care provided to 15,163 cervical cancer patients was examined using 10 measurable QIs. The adherence rate ranged from 50.0% for ‘cystoscope or proctoscope for stage IVA’ to 98.8% for ‘chemotherapy using platinum for stage IVB’. Despite the variation in care, hospitals reported clinically valid reasons for more than half of the non-adherent cases. Clinically valid reasons accounted for 75%, 90.9%, 73.4%, 44.5%, and 88.1% of presented non-adherent cases respectively. Conclusion Our study revealed variations in pattern of care as well as an adherence to standards-of-care across Japan. Further assessment of the causes of variation and non-adherence can help identify areas where improvements are needed in patient care.

Abstract
Lambert-Eaton myasthenic syndrome (LEMS) is most commonly associated with small cell lung carcinoma, while it is rarely associated with gynecological and breast carcinoma. We herein report a case of LEMS associated with synchronous double cancer, which was a combination of small cell carcinoma of the cervix and breast carcinoma. The early diagnosis and treatment of LEMS are important for achieving a good outcome. The possibility of accompanying paraneoplastic neurological syndrome must be sufficiently considered in gynecology and breast cancer patients. To our knowledge, this is the first report of LEMS associated with synchronous double cancer.

Abstract
Background This open-label phase III trial evaluated efficacy and safety of S-1 plus cisplatin vs. cisplatin alone as first-line chemotherapy in patients with stage IVB, recurrent, or persistent cervical cancer. Methods Patients were randomised (1:1) to S-1 plus cisplatin (study group) or cisplatin alone (control group). In each cycle, cisplatin 50 mg/m2 was administered on Day 1 in both groups. S-1 was administered orally at 80–120 mg daily on Days 1–14 of a 21-day cycle in the study group. The primary endpoint was overall survival (OS). Results A total of 375 patients were enrolled, of whom 364 (188, study group; 176, control group) received treatment. Median OS was 21.9 and 19.5 months in the study and control groups, respectively (log-rank P = 0.125; hazard ratio [HR] 0.84, 95% confidence interval [CI] 0.67–1.05). Median progression-free survival (PFS) was 7.3 and 4.9 months in the study and control groups, respectively (HR 0.62, 95% CI 0.48–0.80, P < 0.001). The adverse event (AE) rate increased in the study group despite the absence of any unexpected AEs. Conclusions S-1 plus cisplatin did not show superiority over cisplatin alone in OS but significantly increased PFS in patients with stage IVB, recurrent, or persistent cervical cancer. Since the standard therapy has changed in the course of this study, further studies are warranted to confirm the clinical positioning of S-1 combined with cisplatin for this population.

Abstract
The purpose of this phase II trial was to assess the efficacy and toxicity of paclitaxel and nedaplatin (TN) as the initial postoperative adjuvant chemotherapy for uterine cervical cancer with lymph node metastases (LNM). Patients with FIGO stage IB1-IIA2 squamous cell carcinoma of the uterine cervix were enrolled. Histological confirmation of LNM was mandatory. Intravenous paclitaxel at 175 mg/m2 and nedaplatin at 80 mg/m2 were administered every 28-day cycle, of which there were 5 cycles after radical hysterectomy. Sixty-two patients were enrolled in the study from November 2011 to July 2015. Their median age was 48.5 years (range 28-64). The median tumor diameter was 37 mm (5-64). Overall, 30 patients (48.4%) had 1 metastatic lymph node, 11 (17.7%) had 2, 3 (4.8%) had 3, 5 (8.1%) had 4, and 13 (21.0%) had 5 or more. With a median follow-up of 45.7 months (range 23.4-69.5), the 2-year relapse-free survival and 2-year overall survival rates were 79.0% (90% CI, 69.0%-86.2%) and 93.5% (95% CI, 83.7%-97.5%), respectively. Almost all adverse events were relatively mild. Grade 3-4 adverse events (NCI-CTC ver. 4.0) that occurred in 5% or more of patients were neutropenia (60.7%) and infection (6.6%). The proportion of patients who completed 5 cycles of treatment was 90.3%. Postoperative adjuvant chemotherapy with TN for cervical cancer with LNM was demonstrated to be an effective and feasible treatment. A phase III trial is warranted to compare this with concurrent chemoradiotherapy.

Abstract
This phase 1, open-label, dose-escalation study was conducted to determine the safety, tolerability, pharmacokinetics and preliminary efficacy of veliparib with carboplatin and weekly paclitaxel in Japanese women with newly diagnosed, advanced ovarian cancer. Patients received veliparib at 100 or 150 mg b.i.d. on days 1-21 with carboplatin (area under the concentration-time curve 6 mg/mL•min) on day 1 and paclitaxel 80 mg/m2 on days 1, 8 and 15 every 3 weeks for up to 6 21-day cycles. Dose escalation followed a 3 + 3 design to determine dose-limiting toxicities, maximum tolerated dose and the recommended phase 2 dose. Nine patients (median age 62 [range 27-72] years) received a median of 5 (range 3-6) cycles of treatment (3 at 100 mg, 6 at 150 mg). There were no dose-limiting toxicities. The most common adverse events of any grade were neutropenia (100%), alopecia (89%), peripheral sensory neuropathy (78%), and anemia, nausea and malaise (67% each). Grade 3 or 4 adverse events were associated with myelosuppression. Pharmacokinetics of carboplatin/paclitaxel were similar at both veliparib doses. Response, assessed in five patients, was partial in four and complete in one (objective response rate 100%). The response could not be assessed in four patients who had no measurable disease at baseline. The recommended phase 2 dose of veliparib, when combined with carboplatin/paclitaxel, is 150 mg b.i.d. Findings from this phase 1 trial demonstrate the tolerability and safety of veliparib with carboplatin/paclitaxel, a regimen with potential clinical benefit in Japanese women with ovarian cancer.

Abstract
BACKGROUND The prevalence of brain metastases (BM) from uterine cancer has recently increased because of the improvement of overall survival (OS) of patients with uterine cancer due to its early detection and improved local control as a result of new effective treatments. However, little information is available regarding their clinical characteristics and prognosis, because oncologists have encountered BM from uterine cancer on rare occasions. METHODS Records from 81 patients with uterine BM were collected from 10 institutes in Japan. These were used in a multi-institutional study to identify prognostic factors and develop a graded prognostic assessment (GPA) for patients with BM from uterine cancer. RESULTS Median OS after the development of BM was 7 months (95% confidence interval, 4 to 10 months). Multivariate analysis revealed that there were survival differences according to the existence of extracranial metastases and number of BM. In the present uterine-GPA, a score of 0 was assigned to those patients with ≥5 BM and extracranial metastasis, a score of 2 was assigned to those patients with one to four BM or without extracranial metastasis, and a score of 4 was assigned to those patients with one to four BM and without extracranial metastasis. The median OS for patients with a uterine-GPA scores of 0, 2, and 4 was 3, 7, and 22 months, respectively. A survival analysis confirmed the presence of statistically significant differences between these groups (p < 0.05). The results were validated by data obtained from the National Report of Brain Tumor Registry of Japan. CONCLUSION Uterine GPA incorporates two simple clinical parameters of high prognostic significance and can be used to predict the expected survival times in patients with BM from uterine cancer. Its use may help in determining an appropriate treatment for individual patients with BM.

Abstract
5527 Background: A combination of S-1, an oral fluoropyrimidine, plus cisplatin has been used for advanced gastric cancer in Asia and EU, and lung cancer in Japan. It also evaluated in advanced or recurrent cervical cancer in a phase II setting. We conducted a randomized phase III trial to compare the efficacy and safety of S-1 plus cisplatin with those of cisplatin alone in recurrent or persistent after treatment and FIGO IVB cervical cancer patients. Methods: Stage IVB, recurrent or persistent cervical cancer patients aged ≥ 20 years, ECOG PS 0–1 and adequate organ function were randomly assigned (1:1) to receive S-1 (80–120 mg daily, according to BSA, day 1–14) plus cisplatin (50 mg/m2 on day 1) (study group) or cisplatin alone (50 mg/m2 on day 1) (control group) every 3 weeks. Treatment was continued until disease progression. In all, 360 patients (at least 296 events) with a hazard ratio (HR) for death of 0.72 were required for a two-sided alpha of 5% and power of 80% under 2 years of recruitment and 1.5 years of follow-up. Stratification factors included recurrence in previously irradiated field, previous platinum-based therapy, and institution. Primary endpoint was OS based on intent-to-treat principle, and secondary endpoints were PFS, overall response rate (ORR), and safety. Results: In all, 375 patients were assigned to the study (n = 189) and control (n = 186) groups. Rate of previous platinum-based therapy was 64%. The median survival time was 21.9 and 19.5 months (95% CI, 18.6–25.8 and 17.0–24.3) with the use of unstratified log-rank test in the study and control groups, respectively (log-rank P = 0.125; HR, 0.84; 95% CI, 0.67–1.05). Significant increases in median PFS (7.3 vs. 4.9 months; log-rank P < 0.001; HR, 0.62) and ORR (43.8 vs. 20.1%, P < 0.001) were observed in the study group. Adverse events (grade≥3) were frequent in the study group (80.9 vs. 41.7%) with neutropenia (52.7%), anemia (34.6%), and leukopenia (32.4%) being the most common events. Conclusions: Compared with cisplatin alone, S-1 plus cisplatin did not significantly improve OS but increased ORR, prolonged PFS, and had tolerable safety of patients with stage IVB, recurrent or persistent cervical cancer. Clinical trial information: NCT00770874.

Abstract
e17075 Background: This study aimed to investigate the efficacy and safety of Nedaplatin single therapy for patients with platinum-resistant ovarian, tubal and primary peritoneal cancer after completing standard chemotherapy. Methods: From September 2002 to August 2016, 30 patients who were diagnosed with platinum-resistant ovarian cancer, were treated with Nedaplatin single therapy after completing all standard chemotherapy at our institution. Nedaplatin (80-100mg/m2) was adiministered intravenously on day 1 of a 28 day cycle. We retrospectively investigated the response rate, toxicities, and survival based on the use of Nedaplatin single therapy. Results: The median age was 58.5 years (23-76). The median number of prior chemotherapy regimen was 3 (1-7). The median platinum-free interval between the final use of platinum analogues and starting Nedaplatin single therapy was 9.4 months (0.9-54.9). Among 22 patients who had measurable disease, 8 (36.4%) responded partially to Nedaplatin single therapy. Seven patients (23.3%) experienced hematological toxicities of Grade 3/4. Six patients (20.0%) experienced non-hematological toxicities Grade 2. No treatment-related death occurred. The median progression-free survival was 3.2 months (0-23.3), and over all survival was 9.2 months (1.1-56.4) after treatment with Nedaplatin single therapy. Age (<70 years, p=0.017) and platinum-free interval (<6 months, p=0.013) were the prognosis factors for survival in univariate analyses. Conclusions: Nedaplatin single therapy seemed to be an effective and safe chemotherapy regimen for platinum-resistant ovarian cancer after completing standard chemotherapy.

The issues regarding postoperative adjuvant therapy and prognostic risk factors for patients with stage I-II cervical cancer: A review. J Obstet Gynaecol Res 2017; 43:617-626. [PMID: 28190285 DOI: 10.1111/jog.13282] [Citation(s) in RCA: 30] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2016] [Revised: 11/10/2016] [Accepted: 12/18/2016] [Indexed: 11/30/2022]
Abstract
The treatment for most patients with early-stage cervical cancer involves radical hysterectomy and pelvic lymph node dissection, and indications for postoperative adjuvant therapy have been determined by evaluating the prognostic risk factors for recurrence in each case. The aim of this review is to raise and discuss the various issues that have not yet been resolved regarding the prognostic risk factors and postoperative adjuvant therapy. Several clinicopathological factors, such as tumor size, lymphovascular space involvement, deep stromal invasion, parametrial involvement and lymph node metastasis, have been identified to have prognostic significance in early-stage cervical cancer. However, this remains controversial because there is suggested to be substantial heterogeneity among patients after radical hysterectomy and lymphadenectomy and it would be difficult to define the risk groups clearly. This indicates the need to develop more convenient and accurate criteria to define risk groups. According to the currently available evidence, patients in the high-risk group should receive adjuvant concurrent chemoradiotherapy (CCRT) with cisplatin (CDDP) and fluolouracil. However, CCRT with CDDP administered weekly (CCRT-P) has instead been applied in a clinical context worldwide. Whether CCRT-P has a survival benefit compared with radiotherapy (RT) alone is unknown because no randomized phase III trials have been performed for patients in the high-risk group after radical surgery. Patients with high-risk factors have a high incidence of distant metastasis, for whom systemic chemotherapy might be a key to improving overall survival. The pivotal study that investigated the role of RT alone for patients with intermediate-risk factors after hysterectomy is the GOG092 trial. This trial showed a 47% reduction in the risk of recurrence after RT compared with no further treatment (NFT). However, the improvement in overall survival with RT did not reach statistical significance, while patients allocated to the RT group did experience an increase in severe toxicities compared with the NFT group. This could be why many physicians are reluctant to treat patients with this approach, although guidelines recommend RT for patients with intermediate-risk factors. With regard to toxicities, postoperative RT would be problematic because the organs in the pelvis targeted by RT have already been damaged by radical surgery. To reduce the toxicities, intensity-modulated radiotherapy would best be used worldwide. Further improvement in adjuvant therapy will come from enhanced definition of prognostic risk factors, better patient selection, and refinements in both local and systematic therapies.

Abstract
PURPOSE Binimetinib is a potent, selective MEK1/2 inhibitor with demonstrated efficacy against BRAF- and RAS-mutant tumors. Retinal adverse events associated with MEK inhibitors have been reported in some cases. The aim of this study was to assess single-agent binimetinib, with detailed ophthalmologic monitoring, in Japanese patients with advanced solid tumors. METHODS This was an open-label phase I dose-escalation and dose-expansion study (NCT01469130). Adult patients with histologically confirmed, evaluable, advanced solid tumors were enrolled and treated with binimetinib 30 or 45 mg twice daily (BID). The primary objective was to determine the maximum tolerated dose (MTD) and/or recommended phase II dose (RP2D) of single-agent binimetinib in Japanese patients. RESULTS Twenty-one patients were enrolled; 3 and 8 patients had documented BRAF and KRAS mutations, respectively. Two of 6 patients (33 %) receiving binimetinib 45 mg BID in dose-escalation experienced recurrent grade 2 retinal adverse events (AEs) which were reversible, and this dose was declared the MTD and RP2D. All patients experienced ≥1 AE suspected to be treatment related; the most common (>50 %) were blood creatine phosphokinase increase (76 %), retinal detachment and aspartate aminotransferase increase (62 % each), and diarrhea (52 %). There were no complete or partial responses; 14 patients (67 %) had stable disease, which lasted >180 days in 5 patients. Expression of phospho-ERK decreased in the skin following binimetinib treatment at both dose levels, indicating target inhibition. CONCLUSIONS Binimetinib demonstrated efficacy and acceptable safety in Japanese patients with solid tumors, supporting the 45 mg BID dose of binimetinib as the RP2D.

Abstract
Objective The concept of platinum sensitivity and cross-resistance among platinum agents are widely known in the management of recurrent ovarian cancer. The aim of this study was to evaluate two hypotheses regarding the validity of the concept of platinum sensitivity and non-cross-resistance of cisplatin analogue with cisplatin in recurrent cervical cancer. Methods In this retrospective study, the clinical data of patients with recurrent cervical cancer, who had a history of receiving cisplatin based chemotherapy (including concurrent chemoradiotherapy [CCRT] with cisplatin) and who received second-line chemotherapy at the time of recurrence between April 2004 and July 2012 were reviewed. Results In total, 49 patients-34 squamous cell carcinomas (69.4%) and 15 non-squamous cell carcinomas (30.6%)-were enrolled. The median age was 53 years (range, 26 to 79 years). Univariate and multivariate analysis showed that a platinum free interval (PFI) of 12 months has a strong relationship with the response rate to second-line chemotherapy. Upon multivariate analysis of survival after second-line platinum-based chemotherapy, a PFI of 12 months significantly influenced both progression-free survival (hazard ratio [HR], 0.349; 95% confidence interval [CI], 0.140 to 0.871; p=0.024) and overall survival (HR, 0.322; 95% CI, 0.123 to 0.842; p=0.021). In patients with a PFI of less than 6 months, the difference of progression-free survival between patients with re-administration of cisplatin (3.0 months) and administration of cisplatin analogue (7.2 months) as second-line chemotherapy was statistically significant (p=0.049, log-rank test). Conclusion The concept of platinum sensitivity could be applied to recurrent cervical cancer and there is a possibility of noncross-resistance of cisplatin analogue with cisplatin.

Abstract
BACKGROUND The aims of this study were to evaluate the efficacy and toxicity of chemotherapy (CT) compared with concurrent chemoradiotherapy (CCRT) after radical hysterectomy and lymphadenectomy in high-risk patients with early-stage cervical cancer and to evaluate whether the radicality of the lymphadenectomy would affect the outcome and toxicity of postoperative adjuvant therapy. METHODS The cases of all patients (n = 393) with FIGO IB1-IIB cervical cancer who were treated by radical surgery at Shizuoka Cancer Center between January 2002 and December 2013 were reviewed. Of these, 111 patients met the inclusion criteria for this retrospective study: (1) high risk for occurrence due to pathologically confirmed parametrial invasion and/or pelvic lymph node metastasis; (2) postoperative treatment with adjuvant CT or CCRT. The clinical data of these patients were reviewed. RESULTS Of the 111 patients, 37 and 74 patients underwent CT and CCRT, respectively. The 4-year progression-free survival rate [PFS; 71.7 (CT) vs. 68.3 % (CCRT)] and overall survival rate [76.0 (CT) vs. 82.7 % (CCRT)] did not differ significantly between the two groups. The CT group contained significantly more patients with severe neutropenia than the CCRT group (66.7 vs. 23.0 %, respectively; p < 0.001), and the CCRT group contained significantly more patients with diarrhea than the CT group (10.8 vs. 0 %, respectively; p = 0.04). The patients who had ≥40 lymph nodes dissected (≥40 group) had higher PFS than the patients who had <40 lymph nodes dissected (<40 group) (73.2 vs. 64.2 %, respectively), although the difference was not significant. In the CT group, there was no significant association between the number of dissected lymph nodes and severe toxicities. However, in the CCRT group, significantly more vomiting (p = 0.046) and edema (p = 0.046) occurred in the ≥40 group than in the <40 group. CONCLUSIONS Chemotherapy after surgery for high-risk patients had similar efficacy and a different toxicity profile compared with CCRT, and a more radical surgical procedure would improve the survival outcome. However, CCRT was associated with worse toxicity than CT. We advocate a prospective randomized study to compare CT with CCRT for patients with high-risk factors for recurrence.

Abstract
OBJECTIVE A multicenter phase II trial was conducted to assess the efficacy and toxicity of concurrent chemoradiotherapy (CCRT) with weekly cisplatin (CDDP) and paclitaxel (PTX) in patients with locally advanced uterine cervical cancer. METHODS Patients with FIGO stage III-IVA uterine cervical cancer without para-aortic lymphadenopathy were enrolled. Patients received definitive radiotherapy (RT) consisting of external beam whole-pelvic RT and high-dose-rate intracavitary brachytherapy. The cumulative linear quadratic equivalent dose was 62-65Gy prescribed at point A. weekly CDDP at 30mg/m(2) and PTX at 50mg/m(2) were administered concurrently with RT for ≥5 courses. RESULTS Sixty-eight of the 70 registered patients were eligible. The complete response rate was 76.5% (95% confidence interval [CI], 66.4-86.6%). With a median follow-up of 27months (range, 7.9-33.5), the 2-year cumulative progression-free survival and the 2-year cumulative overall survival rates were 83.8% (95% CI, 75.1-92.6%) and 92.7% (95% CI, 86.4-98.9%), respectively. The pelvic cumulative disease progression-free and the 2-year cumulative distant metastasis rates were 89.6% (95% CI, 82.3-96.9%) and 13.2% (95% CI, 5.2-21.3%), respectively. The 2-year cumulative late complication rates were 25% for all grades, 13.2% for grade 1, 5.9% for grade 2, 2.9% for grade 3, and 2.9% for grade 4. CONCLUSIONS For locally advanced cervical cancer, CCRT with weekly CDDP 30mg/m(2) and PTX at 50mg/m(2) demonstrated favorable antitumor activity, and was feasible and safe with respect to the protocol-specified serious adverse reactions and events. Evaluation of this regimen in phase III trials is warranted.

Abstract
AIM The aim of this retrospective study was to analyze data for patients with stage IB-IIB uterine cervical cancer who were treated with concurrent chemoradiotherapy with fluorouracil (5-FU) and cisplatin (CCRT-FP) as postoperative adjuvant therapy and to re-examine these issues and further treatment. METHODS Patients with high risk for recurrence underwent CCRT-FP as postoperative adjuvant therapy. A total of 73 patients who met these criteria were included in this study. Data related to survival, toxicity, and treatment feasibility were analyzed, and the question of whether there were differences in survival and toxicity according to the number of dissected lymph nodes at surgery was evaluated. RESULTS Median patient age was 45 years (range, 24-67 years). Two-thirds of patients had squamous cell histologic type, 41 patients (56.2%) had parametrial invasion, and 60 patients (82.2%) had lymph node metastases. Estimated 4-year progression-free survival, overall survival, and local control rates were 71.8%, 84.1%, and 88.5%, respectively. Sixteen patients (21.9%) had grade 3-4 neutropenia and one of them died of septic shock. Non-hematological toxicities were also common: 13 (17.8%) experienced grade 3-4 nausea, and nine (12.3%) experienced grade 3-4 diarrhea. Ileus occurred in 17 patients (23.3%), and seven of them (9.6%) were not yet cured. One patient experienced gastrointestinal perforation. CONCLUSIONS CCRT-FP in the postoperative setting resulted in good survival outcome but toxicity remained problematic. Development of appropriate treatment for patients with high-risk prognostic factors after radical hysterectomy and lymphadenectomy is required.
