Association between financial toxicity and health-related quality of life of patients with gynecologic cancer.

OBJECTIVES: Patients often struggle with their financial situation during cancer treatment due to treatment-related costs or loss of income. This resulting negative effect is called financial toxicity, which is a known as a side effect of cancer care. This study aimed to evaluate the association between financial toxicity and health-related quality of life among patients with gynecologic cancer using validated questionnaires. METHODS: In this multicenter study, patients with gynecologic cancer receiving anti-cancer drug treatment for > 2 months were recruited. Patients answered the COmprehensive Score for Financial Toxicity (COST) tool, EORTC-QLQ-C30, disease-specific tools (EORTC-QLQ-OV28/CX24/EN24), and EQ-5D-5L. Spearman's rank correlation coefficient was used to determine associations. RESULTS: Between April 2019 and July 2021, 109 cancer patients completed the COST questionnaire. The mean COST score was 19.82. Strong associations were observed between financial difficulty (r = - 0.616) in the EORTC-QLQ-C30 and body image (r = 0.738) in the EORTC-QLQ-CX24, while weak associations were noted between the global health status/quality of life (r = 0.207), EQ-5D-5L index score (r = 0.252), and several function and symptom scale scores with the COST score. CONCLUSIONS: Greater financial toxicity was associated with worse health-related quality of life scores, such as financial difficulty in gynecologic cancer patients and body image in cervical cancer patients as strong associations, and weakly associated with general health-related quality of life scores and several function/symptom scales.

Neoadjuvant chemotherapy followed by interval debulking surgery for advanced epithelial ovarian cancer: GOTIC-019 study.

INTRODUCTION: Three randomized controlled trials have resulted in extremely extensive application of the strategy of using neoadjuvant chemotherapy (NAC) followed by interval debulking surgery (IDS) for patients with advanced epithelial ovarian cancer in Japan. This study aimed to evaluate the status and effectiveness of treatment strategies using NAC followed by IDS in Japanese clinical practice. PATIENTS AND METHODS: We conducted a multi-institutional observational study of 940 women with Federation of Gynecology and Obstetrics (FIGO) stages III-IV epithelial ovarian cancer treated at one of nine centers between 2010 and 2015. Progression-free survival (PFS) and overall survival (OS) were compared between 486 propensity-score matched participants who underwent NAC followed by IDS and primary debulking surgery (PDS) followed by adjuvant chemotherapy. RESULTS: Patients with FIGO stage IIIC receiving NAC had a shorter OS (median OS: 48.1 vs. 68.2 months, hazard ratio [HR]: 1.34; 95% confidence interval [CI] 0.99-1.82, p = 0.06) but not PFS (median PFS: 19.7 vs. 19.4 months, HR: 1.02; 95% CI: 0.80-1.31, p = 0.88). However, patients with FIGO stage IV receiving NAC and PDS had comparable PFS (median PFS: 16.6 vs. 14.7 months, HR: 1.07 95% CI: 0.74-1.53, p = 0.73) and OS (median PFS: 45.2 vs. 35.7 months, HR: 0.98; 95% CI: 0.65-1.47, p = 0.93). CONCLUSIONS: NAC followed by IDS did not improve survival. In patients with FIGO stage IIIC, NAC may be associated with a shorter OS.

Validity of the COmprehensive Score for financial Toxicity (COST) in patients with gynecologic cancer.

OBJECTIVE: Financial toxicity is a financial burden of cancer care itself, which leads to worse quality of life and higher mortality and is considered an adverse effect. The COmprehensive Score for financial Toxicity (COST) tool is a patient-reported outcome measurement used to evaluate financial toxicity. We aimed to validate the internal consistency and reproducibility of the COST tool in patients with gynecologic cancer. METHODS: In this multicenter study covering the period April 2019 to July 2021, using the COST tool in Japan, patients diagnosed with ovarian, cervical, or endometrial cancer receiving systemic anti-cancer drug therapy for more than 2 months were eligible. Patients with no out-of-pocket costs for direct medical costs were excluded. The patients answered the initial test and a retest, which was completed from 2 to 14 days after the initial test. Internal consistency and reproducibility were assessed using Cronbach's alpha and intraclass correlation coefficient (ICC), respectively. Cronbach's alpha ≥0.8 indicates good internal consistency, and ICC ≥0.8 is highly reliable. RESULTS: A total of 112 patients (ovarian: 50, cervical: 26, endometrial: 36) responded to the initial test, and 89 patients answered the retest from 2 to 14 days after the initial test. The median patient age was 58 (range, 28-78) years. The median COST score was 19. Cronbach's alpha showed good internal consistency at 0.83 (95% CI 0.78 to 0.87). The ICC at 0.850 (95% CI 0.777 to 0.900) showed high reliability. CONCLUSIONS: The COST tool has good internal consistency and reliable reproducibility in patients with gynecologic cancer in Japan. The COST tool quantifies financial toxicity in the insurance system, where patients have limited out-of-pocket direct medical costs. The results support the use of the COST tool in patients with gynecologic cancer.

Effect of prior olaparib maintenance therapy for platinum sensitive recurrent ovarian cancer on response to subsequent platinum-based chemotherapy.

AIM: Several years have passed since olaparib maintenance therapy was approved in patients with platinum sensitive recurrent ovarian cancer (PSROC). We speculated that the response to platinum-based chemotherapy (PBC) would be impaired at the time of recurrence after olaparib maintenance therapy. We conducted a noninterventional retrospective study to clarify this clinical question in a single institution. METHODS: We included all patients with PSROC who received olaparib after second or later line of PBC between April 18, 2018, and August 31, 2021. We evaluated the effect of olaparib maintenance therapy on PBC after progression. RESULTS: We identified 42 patients who received olaparib maintenance therapy after second or later line of PBC. Twenty-four patients relapsed after olaparib maintenance therapy, and 17 patients received PBC again. Four of 17 patients (complete response 2, partial response 2) responded to the PBC. The median progression-free survival was longer in patients with platinum-free interval ≥12 months than platinum-free interval of 6-12 months (9.7 vs 2.6 months, hazard ratio, 0.20: 95% confidence interval, 0.04-0.90; p = 0.04). CONCLUSIONS: In the patients with PSROC who experienced disease progression after olaparib maintenance therapy, especially in those with platinum-free interval of 6-12 months, the response to subsequent PBC was extremely poor. The efficiency of re-administration of PBC for PSROC patients with a short-term recurrence after olaparib treatment may need to be reconsidered.

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

BACKGROUND: We evaluated the survival effect of adjuvant concurrent chemoradiotherapy after radical hysterectomy in patients with clinical pelvic node-positive cervical adenocarcinoma. METHODS: Patients with pelvic node-positive cervical adenocarcinoma diagnosed between 2000 and 2016 at our institution were identified. Survival was compared between patients who underwent radical hysterectomy alone and those who received concurrent chemoradiotherapy as an adjuvant treatment. Survival analysis using log-rank test and Cox proportional hazards model was performed. RESULTS: We identified 80 patients who underwent radical hysterectomy for clinical pelvic node-positive cervical adenocarcinoma; of these, four with pathological pelvic node-negative adenocarcinoma were excluded. Of the 76 patients, 27 underwent radical hysterectomy alone and 49 received radical hysterectomy followed by concurrent chemoradiotherapy. With a median follow-up of 53 months, the 5-year overall survival rate was 51.0% in patients who underwent radical hysterectomy alone versus 53.0% in patients who received additional concurrent chemoradiotherapy (log-rank p = 0.455). CONCLUSION: The addition of concurrent chemoradiotherapy after radical hysterectomy did not significantly improve survival among patients with pelvic node-positive cervical adenocarcinoma. More appropriate treatment strategies are needed to improve the survival outcomes of these patients.

Treatment strategy for locally advanced squamous cell cervical cancer with clinically positive pelvic lymph nodes metastasis.

AIM: To determine the optimal treatment for locally advanced squamous cell cervical cancer with clinical positive pelvic lymph nodes metastasis (cN1). METHODS: We enrolled patients with squamous cell cervical cancer with 2008 FIGO stages IB, IIA, or IIB diagnosed with cN1, who were treated at Hyogo Cancer Center between April 2010 and December 2016. Patients with para-aortic lymph nodes metastasis were excluded. RESULTS: Of the 69 eligible patients, 24 underwent concurrent chemoradiotherapy (CCRT), 11 underwent radical hysterectomy with pelvic lymphadenectomy (RH) with or without adjuvant RT, and 34 underwent neoadjuvant chemotherapy (NAC) followed by RH as initial treatment. The regimens of NAC included dose-dense TC (paclitaxel 80 mg/m2 , days 1, 8, 15; and carboplatin at an area under the curve = 6 on day 1, every 3 weeks) and dose-dense TP (paclitaxel 80 mg/m2 on days 1, 8, 15; and cisplatin 75 mg/m2 on day 1, every 3 weeks). The median observation period was 57 (12-107) months. The 5-year disease-free survival rates of the CCRT, RH, and NAC groups were 78.7%, 63.6%, and 88.2%, respectively (p = 0.14). The 5-year overall survival rates of the CCRT, RH, and NAC groups were 78.6%, 70.1%, and 94.1%, respectively (p = 0.11). CONCLUSIONS: We recommend avoiding RH as primary treatment for cN1 with locally advanced squamous cell cervical cancer. Although CCRT should be considered for cN1, further studies are required to determine if NAC followed by RH will serve as an effective option.

Quality of life assessment of cell-free and concentrated ascites reinfusion therapy during initial treatment for advanced ovarian cancer: A prospective cohort study.

AIM: Cell-free and concentrated ascites reinfusion therapy (CART) is applied to relieve symptoms in patients with malignant ascites. We performed a prospective cohort study to evaluate the efficacy and safety of CART performed on patients with advanced ovarian and peritoneal cancers with massive ascites during the initial treatment. METHODS: From April 2018 to July 2020, CART was performed during the initial treatment of 31 patients with advanced ovarian and peritoneal cancers with cancerous ascites. Patient characteristics and clinical information before and after CART were collected. We performed quality of life assessment using the Japanese version of the M.D. Anderson Symptom Inventory (MDASI-J) 24 h before and after CART. RESULTS: CART was performed 38 times in 24 patients before or during neoadjuvant chemotherapy and 11 times in 11 patients prior to surgery. Four patients underwent CART before primary surgery and before and/or during chemotherapy. Grade 1-2 fever was observed in 18 of 31 cases (58%), and all were controllable by nonsteroidal anti-inflammatory drugs. CART did not adversely affect the main treatment, chemotherapy, or surgery. CART significantly improved the MDASI-J symptom and interference scores within 24 h after the procedure. The symptom and interference scores decreased from 2.4 to 1.8 and from 4.8 to 3.0, respectively. CONCLUSIONS: CART can be safely performed and is useful for symptom relief and improvement of general condition prior to initial surgery and during initial chemotherapy in ovarian and peritoneal cancers. Performing CART at the time of initial treatment may facilitate initiation of the main treatment.

Suppressive effect upon carboplatin hypersensitivity reaction via pegylated liposomal doxorubicin combination therapy.

BACKGROUND: Occurrence of hypersensitivity reaction (HSR) in patients having received multiple doses of carboplatin has been reported. Several studies demonstrated reduction of carboplatin-associated HSR with in combination with pegylated liposomal doxorubicin (PLD). The objective of this study was to determine the suppressive effect on carboplatin-induced HSR via combined treatment with PLD within clinical practice. METHODS: We reviewed the medical records of women with primary or recurrent ovarian, fallopian tube, or peritoneal cancer treated with carboplatin containing regimen at our hospital between January 2009 and March 2019. We compared the incidence of carboplatin-induced HSR among patients who received more than one cycle of PLD plus carboplatin (PLD-C) therapy (i.e., PLD-C group) versus patients who never received PLD-C therapy (non-PLD-C group). RESULTS: A total of 414 women were included in this study (48: PLD-C group, 366: non-PLD-C group). Carboplatin-induced HSR occurred in 34 total patients (8.2%) [1/48 (2.1%) in the PLD-C group and 33/366 (9.0%) in the non-PLD-C group], with a median cycle number of carboplatin administration at onset of HSR being 9. Incidences of carboplatin-induced HSR within the PLD-C versus non-PLD-C group at the 8th, 12th, and 16th cycles of carboplatin administration were 2.2% vs 11.2%, 2.2% vs 28.6%, and 2.2% vs 39.1%, respectively [hazard ratio: 19.2 (95% confidence interval: 9.82-39.4), p < 0.0001]. CONCLUSION: Based on the data analyzed here, a suppressive effect on carboplatin-induced HSR via combination therapy with PLD was confirmed within clinical practice.

Dose-dense paclitaxel and carboplatin vs. conventional paclitaxel and carboplatin as neoadjuvant chemotherapy for advanced epithelial ovarian, fallopian tube, or primary peritoneal cancer: a retrospective study.

BACKGROUND: The purpose of this study was to determine the optimal regimen of neoadjuvant chemotherapy (NAC) for advanced epithelial ovarian, fallopian tube, and peritoneal cancers. METHODS: A clinical information survey involving 171 patients with advanced epithelial ovarian, fallopian tube, or primary peritoneal cancer was conducted. These patients underwent NAC followed by interval debulking surgery at the Hyogo Cancer Center (Hyogo, Japan) between January 2006 and December 2015. RESULTS: The median observation period was 41 (range 4-138) months. Dose-dense paclitaxel and carboplatin (TC) was administered in 101 patients (59%); tri-weekly TC was administered 70 patients (41%). Median progression-free survival was 21 [95% confidence interval (CI) 18-23] months and 15 (95% CI 13-17) months in the dose-dense TC and conventional-TC group [hazard ratio (HR) = 0.69, 95% CI 0.46-0.96; p = 0.02], respectively. The median overall survival was 59 (95% CI 46-72) and 40 (95% CI 32-57) months in the dose-dense TC group and conventional-TC group (HR = 0.72, 95% CI 0.48-1.06; p = 0.09). Multivariate analysis for progression-free survival demonstrated that dose-dense TC represented an independent prognostic factor (HR = 0.70, 95% CI 0.50-0.99; p = 0.04). CONCLUSIONS: Dose-dense TC is a promising regimen of NAC for advanced epithelial ovarian cancer.

Phase II trial of paclitaxel, carboplatin, and bevacizumab for advanced or recurrent cervical cancer.

OBJECTIVE: We evaluated the efficacy and safety of the combination of paclitaxel, carboplatin, and bevacizumab in patients with advanced or recurrent cervical cancer. METHODS: Subjects included patients with advanced or recurrent cervical cancer not amenable to curative treatment with surgery or radiation therapy. Treatment consisted of paclitaxel 175 mg/m2, carboplatin area under the curve 6 mg/mL/min, and bevacizumab 15 mg/kg every 21 days until disease progression, complete remission, or limiting toxicity. The primary endpoint was the objective response. RESULTS: In total, 34 patients received a median of 6 treatment cycles (range 2-25). The median follow-up period was 18.5 months (range 2-29). The objective response was 88% (95% confidence interval: 72.5%-96.7%). Seventeen patients (50%) experienced complete response, whereas 13 patients experienced (38%) partial response with a median duration of 6 months. Grades 3 and 4 hematologic toxicities manifested as neutropenia in 14 (41.2%), leukopenia in 14 (41.2%), anemia in 11 (32.4%), and thrombocytopenia in 9 (26.5%) patients. One patient who underwent prior pelvic irradiation developed grade 2 rectovaginal fistula. CONCLUSION: The combination of paclitaxel, carboplatin, and bevacizumab is effective and safe in patients with advanced or recurrent cervical cancer.

Is Modified Radical Hysterectomy Needed for Patients with Clinical Stage I/II Endometrial Cancers? A Historical Control Study.

OBJECTIVE: The aim of the present study was to assess whether hysterectomy with wider resection could improve survival by preventing local recurrence. METHODS: Medical charts of the patients with clinical stage I/II endometrial cancers treated at our hospital between 1990 and 2009 were retrospectively analyzed. The primary endpoint was overall survival (OS), and secondary endpoints were progression-free survival (PFS) and adverse effects according to the type of hysterectomy. RESULTS: A total of 247 patients were identified: 46 patients treated with total abdominal hysterectomy (TAH group) and 201 patients with modified radical hysterectomy (mRH group). No significant differences were observed in OS (p = 0.52) and PFS (p = 0.67) between the two groups. Also, there was no significant difference in the distribution of recurrent sites between the two groups. The patients treated with mRH had a longer operation time and more frequently developed severe adverse events, such as blood loss and lymphedema. CONCLUSION: In our cohorts, there were no significant differences in both PFS and OS according to surgical procedures, and the mRH group more frequently developed severe adverse events. Overall, clinical benefit was not obtained by mRH in patients with clinical stage I/II endometrial carcinomas.

A case series title: femoral nerve injury with an episode of motor neuropathy caused by gynecological surgery: a case series.

Background: Although iatrogenic nerve injury is sometimes diagnosed after gynecological surgery, its incidence is underestimated because most cases are self-limiting and underreported. Herein, we report on six cases of femoral nerve injury after gynecological surgery with both sensory and motor neuropathy. Methods: We retrospectively analyzed 785 patients with gynecological cancer requiring surgery, including lymph node dissection, between 2012 and 2016 at our center. The functional damage due to femoral nerve injury was postoperatively assessed and classified according to the Medical Research Council (MRC) scale by an orthopedist and a physiatrist. The eligibility criteria were grade 3 or less hip joint bending and muscular weakness due to nerve injury. Patients were excluded if they had been diagnosed with an isolated sensory disorder. Results: We found six cases (0.76%) of femoral motor neuropathy resulting from gynecological surgery. All six patients underwent laparotomy using energy devices under general anesthesia with epidural anesthesia in the lithotomy position. Four of them recovered fully within 8 months from surgery with either physical therapy or no treatment, while the other two died within a year post-treatment; thus, recovery evaluation could not be accurately performed. Conclusion: Postoperative femoral nerve injury can be diagnosed based on gait disturbances and difficulties climbing stairs. It is difficult to identify risk factors for femoral nerve injury as they may involve a combination of features, such as intraoperative compression with self-retaining retractors, the lithotomy position, and the use of energy devices. The surgeon should be familiar with the nature of energy devices, make every effort to understand the necessary anatomy, and make every effort to avoid femoral nerve injury. Iatrogenic femoral nerve injury caused by gynecological surgery should be further investigated regarding the patients' quality of life postoperatively.

[The impact of systematic lymphadenectomy for early-stage ovarian carcinomas].

Among the 161 cases of pT1 ovarian cancer treated at our hospital during the last 25 years, the impact of systematic lymphadenectomy was evaluated in 93 cases of the pT1N0M0 group(N0 group), 59 cases of the pT1NxM0(Nx group), and 9 cases of the pT1N1M0(N1 group). Significantly greater relapse-free survival(RFS)and overall survival(OS)were observed in 108 cases of the N0+N1 group compared to the Nx group(p=0. 006, p=0. 02). Multivariate analysis showed that systematic lymphadenectomy was a significant prognostic factor(hazard ratio 0. 473(95%CI, 0. 235-0. 951; p=0. 036). The present study suggested the systematic lymphadenectomy had a significant therapeutic effect on pT1 stage ovarian cancers.

A phase II study of the combination chemotherapy of bevacizumab and gemcitabine in women with platinum-resistant recurrent epithelial ovarian, primary peritoneal, or fallopian tube cancer.

INTRODUCTION: Bevacizumab and gemcitabine are key drugs for treating recurrent epithelial ovarian cancer. However, information about the combination of bevacizumab and gemcitabine is insufficient. We conducted a phase II study to assess the feasibility, clinical activity, and toxicity of this combination chemotherapy. METHODS: This study included women with platinum-resistant recurrent epithelial ovarian, primary peritoneal, or fallopian tube cancer who received one to three regimens of platinum-based chemotherapy between April 1, 2015 and December 31, 2018. The patients received bevacizumab 15 mg/kg intravenously on day 1 and gemcitabine 1000 mg/m2 intravenously on days 1 and 8 every 21 days until disease progression or unacceptable toxicity. The primary endpoint was the completion rate of three cycles of chemotherapy. This study was registered in the University Medical Information Network (UMIN) Clinical Trials Registry (UMIN000016619). RESULTS: Among the 19 patients, 18 (95%) received ≥3 and 9 (47%) received ≥6 cycles of the study therapy. The objective response rate was 42% (complete response of 16% and partial response of 26%), and the clinical control rate was 84%. Hematological toxicity included neutropenia grade 3/4 in 9 patients (47%), anemia grade 3/4 in 2 (11%), and thrombocytopenia grade 3/4 in 1 (5%). One patient (5%) had grade 3 hypertension, and 1 (5%) had grade 3 protein urea. Possibly related grade 3 pulmonary toxicity was observed in 1 patient. Three patients needed dose reduction of gemcitabine to 800 mg/m2 due to treatment delay by 15 to 21 days on day1. There was no treatment delay more than 14 days on day 8. The median progression-free survival duration was 5.1 months and median overall survival duration was 21.3 months. CONCLUSION: The combination chemotherapy with gemcitabine and bevacizumab was feasible, effective and safe. This combination chemotherapy may be explored in a further randomized trial.

Combination of irinotecan and platinum for platinum-resistant or refractory recurrent ovarian cancers: A preliminary case series.

Non-platinum single agents are usually used for patients with platinum-resistant recurrent ovarian cancers (ROC). However, the efficacy of these drugs is limited. The aim of the present study was to evaluate the efficacy and adverse events (AE) of combination therapy with irinotecan and platinum (CPT-Pt) for ROC. A total of 28 platinum-resistant or refractory patients with ROC treated with CPT-Pt at the National Defense Medical College Hospital institution between 2002 and 2012 were identified. All patients received taxane and carboplatin (TC) as a first-line treatment and relapsed within 6 months after completion of TC, or progressed during TC therapy. The median age was 59 years (range, 16-78), and median number of CPT-Pt therapy cycles was 5.5 (range, 2-16). The overall response rate was 14%, with a complete response (CR) in 2 patients and partial response (PR) in 2 patients. Stable disease (SD) for >3 months was observed in 15 patients (54%), resulting in a clinical benefit rate (CBR = CR + PR + SD) of 68%. The median progression-free survival and overall survival were 8 and 15 months, respectively. Fifteen cases (68%) developed grade 3/4 hematological AE and 3 cases (11%) developed non-hematological grade 3/4 AE, which were resolved by conservative management or dose reduction. Platinum re-treatment with irinotecan for platinum refractory or resistant ROC may be a candidate in such clinical settings.
