Introduction
Breast cancer (BC) is the most common cancer in women, and the incidence of brain metastasis (BM) from BC ranges from 20% to 30%, with a median survival of 10 to 15 months. Previous reports have shown that the presence of obesity or diabetes negatively impacts survival. The present study investigates the association between obesity or diabetes mellitus (DM) and overall survival of patients with BC with BM.Materials and Methods
A database from 2 referral centers for the period of July 2014 to February 2018 was analyzed. The inclusion criteria were as follows: patients who had a confirmed diagnosis of BC with BM were followed and treated at these centers. Demographic data, body weight and height, clinical and oncologic history, functional status, prognostic scales, and prognoses were examined.Results
A total of 228 patients were included. The median age at BM was 50 years; the median survival after diagnosis was 12.1 months; 108 patients had a body mass index (BMI) ≥ 25, and 40 (17%) patients had DM. The association between survival and the presence of BMI > 25 exhibited a P value of 0.3.Discussion
We found no association between overweight, obesity, or DM and survival in patients with BC with BM. The role of obesity in cancer is a robust research topic, as there are many questions to be answered.Conclusion
Obesity as a prognostic indicator should be further studied, because we found no association between overall survival and either patients with BM from BC with a BMI > 25 or those with normal weight. 相似文献2.

Introduction
Elderly patients are more prone to encounter some adverse factors when they receive chemotherapy compared to younger patients. Addition of rituximab to a reduced dose (RD) of cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP) chemotherapy might improve patient outcomes with an improved toxicity profile when provided to elderly patients with diffuse large B-cell lymphoma.Patients and Methods
A total of 53 patients aged ≥ 65 years with diffuse large B-cell lymphoma diagnosed between August 2012 and December 2014 were enrolled onto this study. RD-R-CHOP regimen consisted of rituximab at 375 mg/m2, cyclophosphamide at 600 mg/m2, doxorubicin at 30 mg/m2, and vincristine at 1 mg on day 1 of each cycle and 40 mg of prednisone on days 1 to 5. Patients received granulocyte colony-stimulating factor if they experienced grade 3/4 neutropenia or febrile neutropenia during any cycle.Results
The median follow-up duration was 18 months (range, 1-44 months). Complete response and overall response rates were 64.1% and 81.1%, respectively. Three-year event-free and overall survival rates were 45.7% ± 8.4% and 62.7% ± 8.1%, respectively. Grade 3/4 neutropenia occurred in 20 patients (37.7%), while febrile neutropenia occurred in 7 patients (20.7%).Conclusion
Outcomes of RD-R-CHOP chemotherapy were comparable to those of standard-dose R-CHOP or previous dose-adjusted R-CHOP chemotherapy. In the future, strategies such as tailored therapy based on geriatric assessment results are needed to determine the chemotherapeutic dosage. 相似文献3.

Background
Anal squamous cell carcinoma (ASCC) is a rare, human papilloma virus-associated cancer. The purpose was to investigate the population-based incidence rates, age and gender distribution, and survival of ASCC.Materials and Methods
All primary ASCC in 1987 to 2016 were identified in the Cancer Registry of Norway (N = 1548), with information on age, gender, stage, county of residence, radiotherapy, and survival.Results
Median age was 66 years; 71% were females. World age-standardized incidence rates increased (1987-2016) from 0.79 (95% confidence interval [CI], 0.69-0.90) to 1.10 (95% CI, 1.00-1.22) per 100,000 person-years in females and, from 0.34 (95% CI, 0.28-0.42) to 0.47 (95% CI, 0.40-0.54) in males. Estimated annual percentage change was 1.7 (95% CI, 0.9-2.6) for females and 1.3 (95% CI, ?0.1 to 2.7) for males. Incidence rates increased with age; the relative risk was higher in major cities. Five-year net survival increased from 63.4% to 72.7% (1987-2016), but for age ≥ 70 years remained ～57%. Net survival was dependant on stage, age, and gender. Five-year net survival (1997-2016) was 76.4% after curative radiotherapy, and 18.0% after palliative radiotherapy.Conclusion
ASCC incidence rates increased from 1987 to 2016, and survival improved for patients < 70 years. Five-year net survival was 76% after curative radiotherapy in Norway. 相似文献4.

Background
Brain metastases (BM) pose a significant problem in patients with metastatic renal-cell carcinoma (mRCC). Local and systemic therapies including stereotactic radiosurgery (SRS) are rapidly evolving, necessitating reassessments of outcomes for modern patient management.Patients and Methods
The mRCC patients with BM treated with SRS were reviewed. Patient demographics, clinical history, and SRS treatment parameters were identified.Results
Among 268 patients with mRCC treated between 2006 and 2015, 38 patients were identified with BM. A total of 243 BM were treated with SRS with 1 to 26 BMs treated per SRS session (median, 2 BMs). The median (range) BM size was 0.6 (0.2-3.1) cm and median (range) SRS treatment dose was 18 (12-24) Gy. Treated BM local control rates at 1 and 2 years were 91.8% (95% confidence interval, 85.7-95.4) and 86.1% (95% confidence interval, 77.1-91.7), respectively. BM control declined for larger tumors. Survival after 1-year was 57.5% (95% CI 40.2-71.4) for all patients. Survival was not statistically different between patients with < 5 BM versus ≥ 5 BM. Survival was prognostic based on International Metastatic Renal Cell Carcinoma Database (IMDC) risk groups in patients with < 5 BM. Two patients experienced grade 3 radiation necrosis requiring surgical intervention.Conclusion
SRS is effective in controlling BM in patients with mRCC. Over half of treated patients survive past a year, and no differences in survival were noted in patients with > 5 metastases. Prognostic risk categories based on systemic disease (IMDC) are predictive of survival in this BM population, with limited rates of symptomatic radiation necrosis. 相似文献5.

Background
The safety and efficacy of targeted therapy in older patients (≥ 70 years) with metastatic colorectal cancer is not well evaluated.Patients and Methods
Outcomes of older patients (including overall survival [OS], progression-free survival [PFS], toxicity, and quality of life [QoL]) were compared to young patients using data from 2 large previously reported clinical trials, CO.17 (cetuximab vs. best supportive care) and CO.20 (cetuximab plus placebo vs. cetuximab plus brivanib). Only patients with wild-type KRAS tumors were included.Results
A total of 251 (26.3%) of 955 patients were ≥ 70 years old. No significant differences in OS, PFS, or grade 3/4 adverse events were observed between older and younger patients treated with cetuximab (or cetuximab with placebo) in either trial. Younger patients trended toward superior OS in both CO.17 (hazard ratio = 1.80; P = .16) and CO.20 (hazard ratio = 1.34; P = .07). QoL maintenance favored younger patients in CO.17 (3.6 vs. 5.7 months; P = .046) but no difference of QoL maintenance was observed in the larger CO.20 trial (1.7 vs. 1.8 months; P = .64). Combination therapy of cetuximab and brivanib was significantly more toxic in older adults (87% vs. 77%; P = .03).Conclusion
OS, PFS, and toxicities were similar between older and younger patients with wild-type KRAS metastatic colorectal cancer when treated with cetuximab. Both age groups likely experience similar QoL maintenance with cetuximab. Dual targeted therapy was significantly more toxic in older patients. 相似文献6.
Purpose
To assess the pharmacologic costs of second-line treatments for metastatic renal-cell cancer (mRCC).Methods
The present evaluation was restricted to pivotal phase 3 randomized controlled trials in second-line for mRCC. We calculated the pharmacologic costs necessary to get the benefit in progression-free survival and overall survival (OS) for each trial. The costs of drugs are at the pharmacy of our hospital and are expressed in euros.Results
Our analysis evaluated 5 phase 3 randomized controlled trials including 3112 patients. The lowest cost per month of progression-free survival and OS gained was associated with the use of cabozantinib (€2006 and €1473, respectively), while everolimus had the highest cost per month of OS gained (€28,590).Conclusion
Combining pharmacologic costs of drugs with the measure of efficacy represented by OS, cabozantinib is a cost-effective second-line treatments for patients with mRCC. 相似文献7.

Introduction
Phase II clinical trials including geriatric assessment (GA) measures are critical for improving the evidence base for older adults with cancer. We assessed the efficacy and tolerability of nab-paclitaxel in older adults with metastatic breast cancer (MBC).Patients and Methods
Patients aged ≥ 65 years with MBC and ≤ 1 previous line of chemotherapy received 100 mg of nab-paclitaxel on days 1, 8, and 15 of a 28-day cycle. A GA was completed pre-chemotherapy, and the validated Cancer and Aging Research Group (CARG) chemotherapy toxicity risk score was calculated. Relationships between tolerability (number of courses, hospitalizations, dose reductions, and toxicity) and risk score were assessed using general linear models, Student t tests, and the Fisher test. Response rate and progression-free survival were evaluated using the Kaplan-Meier method.Results
Forty patients (mean age, 73 years; range, 65-87 years) were included. The median number of cycles was 6, 75% (n = 30) of patients had ≥ 1 dose hold, and 50% (n = 20) had ≥ 1 dose reduction. Fifty-eight percent (n = 23) had treatment-related ≥ grade 3 toxicities, and 30% (n = 12) were hospitalized owing to toxicity. Thirty-five percent (n = 14) responded, and the median progression-free survival was 6.5 months (95% confidence interval, 5.5 months to undefined). Patients with intermediate/high toxicity risk scores had higher risk of grade ≥ 3 toxicity than those with low risk scores (odds ratio, 5.8; 95% confidence interval, 1.3-33.1; P = .01). A higher mean risk score was associated with higher likelihood of dose reductions and hospitalizations.Conclusions
Among older adults with MBC receiving weekly nab-paclitaxel, more than one-half experienced ≥ grade 3 chemotherapy toxicity. However, a GA-based risk score could predict treatment tolerability. 相似文献8.

Introduction
There is substantial evidence for the oncogenic effects of fibroblast growth factor receptor 1 (FGFR1) in many types of cancer, including lung cancer, but the role of this receptor has not been addressed specifically in lung adenocarcinoma.Methods
We performed FGFR1 and EGFR overexpression and co-overexpression assays in adenocarcinoma and in inmortalized lung cell lines, and we also carried out surrogate and interaction assays. We performed monotherapy and combination EGFR/FGFR inhibitor sensitivity assays in vitro and in vivo in cell line– and patient-derived xenografts. We determined FGFR1 mRNA expression in a cohort of patients with anti–EGFR therapy–treated adenocarcinoma.Results
We have reported a cooperative interaction between FGFR1 and EGFR in this context, resulting in increased EGFR activation and oncogenic signaling. We have provided in vitro and in vivo evidence indicating that FGFR1 expression increases tumorigenicity in cells with high EGFR activation in EGFR-mutated and EGFR wild-type models. At the clinical level, we have shown that high FGFR1 expression levels predict higher resistance to erlotinib or gefitinib in a cohort of patients with tyrosine kinase inhibitor–treated EGFR-mutated and EGFR wild-type lung adenocarcinoma. Dual EGFR and FGFR inhibition in FGFR1-overexpressing, EGFR-activated models shows synergistic effects on tumor growth in vitro and in cell line– and patient-derived xenografts, suggesting that patients with tumors bearing these characteristics may benefit from combined EGFR/FGFR inhibition.Conclusion
These results support the extended the use of EGFR inhibitors beyond monotherapy in the EGFR-mutated adenocarcinoma setting in combination with FGFR inhibitors for selected patients with increased FGFR1 overexpression and EGFR activation. 相似文献9.

Introduction
Immunotherapy has revolutionized the treatment of NSCLC, but little is known about the activity of programmed cell death 1 and programmed death ligand 1 blockade across age groups.Methods
We retrospectively evaluated patients with NSCLC who initiated programmed cell death 1 and programmed death ligand 1 inhibitors from January 2013 through July 2017. Medical records and radiographic imaging were reviewed to determine progression-free survival (PFS) and overall survival (OS). We also compared immunotherapy-related toxicities, steroid use, and hospitalizations by age.Results
Of the 245 patients, 26.1% were younger than 60 years, 31.4% were age 60 to 69 years, 31.0% were age 70 to 79 years, and 11.4% were age 80 years or older. The median PFS times by age group were as follows: younger than 60 years, 1.81 months; age 60 to 69 years, 2.53 months; age 70 to 79 years, 3.75 months; and age 80 years or older, 1.64 months (log-rank p value = 0.055). The median OS times by age group were as follows: younger than 60 years, 13.01 months; age 60 to 69 years, 14.56 months; age 70 to 79 years, 12.92 months; and age 80 years or older, 3.62 months (log-rank p value = 0.011). Rates of immunotherapy-related toxicities, steroid use, and hospitalizations did not differ by age.Conclusions
Although the OS and PFS benefits of immunotherapy differ by age, the rates of toxicity are similar regardless of age. 相似文献10.

Background
Eribulin has efficacy in patients with progression after ≥ 1 chemotherapeutic regimen for metastatic breast cancer (MBC). A short disease-free interval (DFI) and previous use of taxanes in the neoadjuvant or adjuvant setting have been associated with worse outcomes for patients receiving first-line chemotherapy for HER2-negative MBC. The aim of the present trial was to evaluate the efficacy and safety of eribulin as first-line therapy for patients with HER2-negative MBC with these poor prognostic factors.Patients and Methods
Eribulin monotherapy was administered until disease progression or unacceptable toxicity. The principal selection criteria were HER2 negativity without previous chemotherapy for MBC, the previous use of taxanes for early-stage breast cancer, and a DFI of < 36 months (subsequently amended to 48 months). The primary endpoint was the investigator-assessed time to progression. The secondary endpoints included overall survival, progression-free survival, objective response rate, clinical benefit rate, duration of response, and toxicity profile. A total of 53 patients were enrolled and received ≥ 1 dose of eribulin.Results
The median patient age was 47 years (range, 23-82.8 years). The median DFI was 15.7 months (range, 0.1-46.4 months). The median investigator-assessed time to progression was 4.1 months (range, 0.2-27.8 months; 95% confidence interval, 3.2-6.2 months). The objective response and clinical benefit rate was 20.8% and 26.4%, respectively. All-grade and grade 3/4 adverse events developed in 96.2% and 69.8% of patients, respectively. The most common treatment-related adverse events were neutropenia, leukopenia, alopecia, nausea, and anemia.Conclusion
Eribulin is effective and safe as first-line therapy for aggressive taxane-pretreated HER2-negative MBC. 相似文献11.

Background
Cardiovascular events (CVEs) have been observed in patients with chronic myeloid leukemia treated with second-generation tyrosine kinase inhibitors.Patients and Methods
We retrospectively evaluated the incidence of CVEs on 233 consecutive patients with chronic myeloid leukemia, of which 116 were treated with imatinib, 75 with dasatinib, and 42 with nilotinib. The median follow-up was 2047, 1712, and 1773 days, respectively.Results
The cumulative incidence of CVEs was 4.29%. Three events occurred during dasatinib treatment, 6 during nilotinib treatment, and none during imatinib treatment (P ≤ .001). Arterial occlusive events occurred in 2 (2.6%) of 75 patients treated with dasatinib and in 6 (14.2%) of 42 patients treated with nilotinib (P ≤ .001). Furthermore, all of them occurred in patients with high-risk (n = 2) and very high-risk (n = 6) cardiovascular risk, contributing to 4.3% of mortality.Conclusion
CVEs were more frequent in patients treated with second-generation tyrosine kinase inhibitors. Arterial occlusive events were more frequent in patients treated with nilotinib, with high and very high cardiovascular risk. 相似文献13.

Background
Colon cancer is the third most frequent cancer diagnosis, and primary payer status has been shown to be associated with treatment modalities and survival in cancer patients. The goal of our study was to determine the between-insurance differences in survival in patients with clinical stage III colon cancer using data from the National Cancer Database (NCDB).Materials and Methods
We identified 130,998 patients with clinical stage III colon cancer in the NCDB diagnosed from 2004 to 2012. Kaplan-Meier curves and multivariable Cox regression models were used to determine the association between insurance status and survival.Results
Patients with private insurance plans were 28%, 30%, and 16% less likely to die than were uninsured patients, Medicaid recipients, and Medicare beneficiaries, respectively. Medicare patients were 14% were less likely to die compared with uninsured patients. Patients receiving chemotherapy were, on average, 65% less likely to die compared with the patients not receiving chemotherapy.Conclusion
Private insurance and a greater socioeconomic status were associated with increased patient survival compared with other insurance plans or the lack of insurance. Future research should continue to unravel how socioeconomic status and insurance status contribute to the quality of care and survival of oncologic patients. 相似文献14.

Introduction
This phase II study evaluated the efficacy and safety of the pan-cyclin–dependent kinase inhibitor roniciclib with platinum-based chemotherapy in patients with extensive-disease SCLC.Methods
In this randomized, double-blind study, unselected patients with previously untreated extensive-disease SCLC received roniciclib, 5 mg, or placebo twice daily according to a 3 days–on, 4 days–off schedule in 21-day cycles, with concomitant cisplatin or carboplatin on day 1 and etoposide on days 1 to 3. The primary end point was progression-free survival. Other end points included overall survival, objective response rate, and safety.Results
A total of 140 patients received treatment: 70 with roniciclib plus chemotherapy and 70 with placebo plus chemotherapy. Median progression-free survival times was 4.9 months (95% confidence interval [CI]: 4.2–5.5) with roniciclib plus chemotherapy and 5.5 months (95% CI: 4.6–5.6) with placebo plus chemotherapy (hazard ratio [HR] = 1.242, 95% CI: 0.820–1.881, p = 0.8653). Median overall survival times was 9.7 months (95% CI: 7.9–11.1) with roniciclib plus chemotherapy and 10.3 months (95% CI: 8.7–11.9) with placebo plus chemotherapy (HR = 1.281, 95% CI: 0.776–1.912, p = 0.7858). The objective response rates were 60.6% with roniciclib plus chemotherapy and 74.6% with placebo plus chemotherapy. Common treatment-emergent adverse events in both groups included nausea, vomiting, and fatigue. Serious treatment-emergent adverse events were more common with roniciclib plus chemotherapy (57.1%) than with placebo plus chemotherapy (38.6%).Conclusions
Roniciclib combined with chemotherapy demonstrated an unfavorable risk-benefit profile in patients with extensive-disease SCLC, and the study was prematurely terminated. 相似文献15.

Introduction
Surgery in SCLC is limited to very early stages, but several reports suggest a potential broader role. Little is known of the influence of microenvironment on the biology of SCLC.Methods
We assessed the clinical prognostic factors in a large series of resected SCLC patients. The prognostic value of programmed cell death ligand 1 (PD-L1) expression in tumor cells and tumor infiltrating lymphocytes (TILs) and the percentage of CD3-, CD20-, CD45- and CD68-positive cells, were also investigated.Results
Two hundred five SCLC cases were resected between 2005 and 2015 and the median follow-up was 29 months (range: 2 to 135 months). Median survival of all patients was 69 months, and 5-year survival rates were 63.8%, 65.5%, 34.9%, and 0% for pathologic stages I, II, III, and IV, respectively. By multivariate analysis complete resection, cigarette index, lymph node metastatic rate, percentage of CD3-positive cells, PD-L1 expression in tumor cells, and TILs were independent prognostic factors. High PD-L1 expression was present in 3.2% and 33.5% of all tumor samples in tumor cells and TILs, respectively. High PD-L1 expression in tumor cells or TILs correlated with shorter survival, whereas high expression of CD3, CD20, and CD45 correlated with better survival.Conclusions
Resected stage II SCLC patients have similar survival as stage I, suggesting that surgery could be extended to patients with hilar lymph node involvement. Survival was better in tumors with a higher percentage of T cells and B cells, whereas PD-L1 expression in tumor cells and TILs correlated with worse survival, which suggests a potential role of immunotherapy in resected SCLC. 相似文献16.

Introduction
Genomic variants that lead to MET proto-oncogenem receptor tyrosine kinase (MET) exon 14 skipping represent a potential targetable molecular abnormality in NSCLC. Consequently, reliable molecular diagnostic approaches that detect these variants are vital for patient care.Methods
We screened tumor samples from patients with NSCLC for MET exon 14 skipping by using two distinct approaches: a DNA-based next-generation sequencing assay that uses an amplicon-mediated target enrichment and an RNA-based next-generation sequencing assay that uses anchored multiplex polymerase chain reaction for target enrichment.Results
The DNA-based approach detected MET exon 14 skipping variants in 11 of 856 NSCLC samples (1.3%). The RNA-based approach detected MET exon 14 skipping in 17 of 404 samples (4.2%), which was a statistically significant increase compared with the DNA-based assay. Among 286 samples tested by both assays, RNA-based testing detected 10 positives, six of which were not detected by the DNA-based assay. Examination of primer binding sites in the DNA-based assay in comparison with published MET exon 14 skipping variants revealed genomic deletion involving primer binding sequences as the likely cause of false negatives. Two samples positive via the DNA-based approach were uninformative via the RNA-based approach due to poor-quality RNA.Conclusions
By circumventing an inherent limitation of DNA-based amplicon-mediated testing, RNA-based analysis detected a higher proportion of MET exon 14 skipping cases. However, RNA-based analysis was highly reliant on RNA quality, which can be suboptimal in some clinical samples. 相似文献17.

Introduction
Electromagnetic navigation bronchoscopy (ENB) is a minimally invasive technology that guides endoscopic tools to pulmonary lesions. ENB has been evaluated primarily in small, single-center studies; thus, the diagnostic yield in a generalizable setting is unknown.Methods
NAVIGATE is a prospective, multicenter, cohort study that evaluated ENB using the superDimension navigation system (Medtronic, Minneapolis, Minnesota). In this United States cohort analysis, 1215 consecutive subjects were enrolled at 29 academic and community sites from April 2015 to August 2016.Results
The median lesion size was 20.0 mm. Fluoroscopy was used in 91% of cases (lesions visible in 60%) and radial endobronchial ultrasound in 57%. The median ENB planning time was 5 minutes; the ENB-specific procedure time was 25 minutes. Among 1157 subjects undergoing ENB-guided biopsy, 94% (1092 of 1157) had navigation completed and tissue obtained. Follow-up was completed in 99% of subjects at 1 month and 80% at 12 months. The 12-month diagnostic yield was 73%. Pathology results of the ENB-aided tissue samples showed malignancy in 44% (484 of 1092). Sensitivity, specificity, positive predictive value, and negative predictive value for malignancy were 69%, 100%, 100%, and 56%, respectively. ENB-related Common Terminology Criteria for Adverse Events grade 2 or higher pneumothoraces (requiring admission or chest tube placement) occurred in 2.9%. The ENB-related Common Terminology Criteria for Adverse Events grade 2 or higher bronchopulmonary hemorrhage and grade 4 or higher respiratory failure rates were 1.5% and 0.7%, respectively.Conclusions
NAVIGATE shows that an ENB-aided diagnosis can be obtained in approximately three-quarters of evaluable patients across a generalizable cohort based on prospective 12-month follow-up in a pragmatic setting with a low procedural complication rate. 相似文献18.

Introduction
Colorectal cancer is a major public health issue, with incidences continuing to rise owing to the growing and aging world population. Current screening strategies for colorectal cancer diagnosis suffer from various limitations, including invasiveness and poor uptake. Consequently, there is an unmet clinical need for a minimally invasive, sensitive, and specific method for detecting the presence of colorectal cancer and pre-malignant lesions.Patients and Methods
An indirect enzyme-linked immunosorbent assay was used to measure the primary (IgM) and secondary (IgG) adaptive humoral immune responses to a panel of previously identified cancer antigens in the sera of normal and adenoma samples, and sera from patients with colorectal cancer.Results
An optimal panel of 7 biomarkers capable of identifying patients with colorectal cancer as distinct from both normal and adenoma samples is identified. The cumulative sensitivity and specificity of the assay are 70.8% and 86.5%, respectively. The positive and negative predictive values of the cohort are 77.3% and 82.1%. This assay was not able to accurately discriminate between normal and adenoma samples. Patients whose serum was positive for the presence of anti-ICLN IgM autoantibodies had a significantly poorer 5-year survival than patients whose serum was negative (P = .004).Conclusion
This study describes a novel minimally invasive enzyme-linked immunosorbent assay-based method, capable of identifying patients with colorectal cancer as distinct from both normal and adenoma samples. Patients are likely to be far more amenable to a blood-based test such as the one described herein, rather than a fecal-based test, likely leading to increased patient uptake. 相似文献19.

Aims
Women treated with pelvic radiation therapy (PRT) for gynaecological or anorectal cancer report a high number of sexual problems and unmet post-treatment psychosexual information needs. Currently, there is suboptimal adherence to recommended rehabilitation aids, such as vaginal dilators, and a paucity of resources to facilitate post-radiation rehabilitation and reduce distress in this population. This randomised controlled trial aimed to evaluate the effectiveness of a study-developed psychosexual rehabilitation booklet in this setting.Materials and methods
Eighty-two women scheduled for PRT to treat gynaecological/anorectal cancer were randomised to receive the intervention booklet (n = 44) or standard information materials (n = 38). Self-report questionnaires administered at pre-treatment baseline and at 3, 6 and 12 months post-treatment assessed adherence with rehabilitation aids, booklet knowledge, anxiety, depression and sexual functioning/satisfaction.Results
Dilator adherence and booklet knowledge were significantly higher in the intervention group than in the control group (averaged over time points), with scores significantly increasing over time. Younger age and gynaecological cancer were significant predictors of greater dilator adherence. No significant group differences were found on psychological and sexual measures.Conclusions
The psychosexual rehabilitation booklet was effective in educating women with gynaecological and anorectal cancers about PRT-related psychosexual side-effects and rehabilitation options, as well as promoting uptake of vaginal dilator use. Future research should elucidate the effectiveness of this booklet in women with greater psychological and sexual functioning needs. 相似文献20.
