Validation of a questionnaire for self-assessment of sexual function and vaginal changes after gynaecological cancer

The Sexual function-Vaginal changes Questionnaire (SVQ), was developed to investigate sexual and vaginal problems in gynaecological cancer patients. The instrument consists of 20 core items, measuring sexual interest, lubrication, orgasm, dyspareunia, vaginal dimensions, intimacy, sexual problems of partner, sexual activity, sexual satisfaction, and body image. Seven additional items assessing current levels of sexual and vaginal problems compared to pre-diagnosis are intended to be used only once in longitudinal studies. The SVQ was validated in two ways: first, the comprehensibility of each item was investigated through combined quantitative and qualitative assessment of patient-observer agreement in 75 gynaecological cancer patients, second, multitrait analyses and principal component analyses were applied to responses from 257 patients with cervical cancer to investigate the scale properties. The level of agreement between the patients' and the observer's ratings was high (median overall agreement 0.84, range 0.46-1.00; median kappa: 0.80, range 0.52-1.00). From the 10 items applicable to all patients, three scales were hypothesized: intimacy, sexual interest and global sexual satisfaction. For sexually active respondents an additional two scales were hypothesized: vaginal changes and sexual functioning. The psychometric analyses confirmed these scales. The internal consistency of the scales ranged 0.76-0.83 (Cronbach's alpha). The study supports the validity and reliability of the SVQ.     

Cardiac mortality and morbidity after breast cancer treatment.

BACKGROUND: Breast conservation treatment for early-stage breast cancer has been demonstrated to be equivalent to mastectomy in a large number of randomized trials. A number of earlier studies of surgery with or without radiation did not show an improvement in overall survival despite large reductions in local recurrence rates. Numerous randomized trials have demonstrated that postmastectomy radiation to the chest wall and regional nodes in high-risk early-stage patients provides improvements in local-regional control and overall survival. METHODS: This article reviews the medical literature pertaining to long-term cardiac toxicity in early-stage breast cancer patients treated with either breast conservation or postmastectomy radiation. RESULTS: A decrease in breast cancer deaths associated with postoperative irradiation was offset by an increase in cardiovascular deaths in early studies. Cardiac toxicity of breast irradiation is a late event, manifesting clinically 10 or more years after breast cancer treatment. The excess deaths were directly related to radiation techniques that exposed excessive volumes of the heart, leading to the development of new techniques designed to shield the heart and reduce the risk of cardiac toxicity. CONCLUSIONS: This review examines the original and contemporary studies of radiation for postmastectomy and breast conservation treatment for early-stage breast cancer, discusses the long-term cardiac mortality and morbidity data from these studies, and reviews the known risk factors associated with cardiac toxicity after irradiation for breast cancer.     

A screening questionnaire for voice problems after treatment of early glottic cancer

PURPOSE: After treatment for early glottic cancer, a considerable number of patients end up with voice problems interfering with daily life activities. A 5-item screening questionnaire was designed for detection of voice impairment. The purpose of this study is to assess psychometric properties of this questionnaire in clinical practice. METHODS AND MATERIALS: The questionnaire was completed by 110 controls without voice complaints and 177 patients after radiotherapy or laser surgery for early glottic cancer. RESULTS: Based on normative data of the controls, a score of 5 or less on at least 1 of the 5 questions was considered to state overall voice impairment. Reliability of the questionnaire proved to be good. Voice impairment was reported in 44% of the patients treated with radiotherapy vs. 29% of the patients treated with endoscopic laser surgery. CONCLUSIONS: The questionnaire proved to be a reliable, valid, and feasible method to detect voice impairment in daily life. The questionnaire is easy to fill in, and interpretation is straightforward. It is useful for both radiation oncologists and otorhinolaryngologists in their follow-up of patients treated for early glottic cancer.     

Radio-chemotherapy as a preoperative treatment for advanced rectal cancer. Evaluation of down-staging and morbidity

BACKGROUND: The standard therapy for patients with clinically resectable rectal cancer is generally considered to be surgery. If the patient is diagnosed with advanced disease, postoperative radio-chemotherapy (RCT) is usually recommended. In our study we aimed to investigate and analyze the effectiveness and toxicity of preoperative pelvic radiotherapy in combination with 5-fluorouracil (5-FU) in locally advanced rectal cancer. PATIENTS AND METHODS: From June 1999 to September 2001 we evaluated 50 consecutive patients [37 male and 13 female; average age 65.1 (range 46-79.5) years] with locally advanced rectal carcinoma. 32 patients were staged as uT3, 14 as uT4, and 4 as uT2. Regarding N-staging, 22 patients were diagnosed as uN0. 2 patients had distant metastases, with liver metastases in both instances. Conformal irradiation was performed with a box technique (4-field technique) with a dose of 45 Gy (5 x 1.8 Gy per week for a total of 25 sessions). From days 1-5 and 29-33, all patients received 5-FU (500 mg/m(2 ) per day, as a continuous i.v. injection). RESULTS: Remission was observed in 28 patients (56%), with down-staging of at least one T-stage. A better success rate was achieved for patients with deep-seated tumors (64% of the patients in this group). Complete remission was observed in 4 patients (8.0%) and progression in 3 (6.0%). 15 patients had no detectable change in tumor staging (30.0%). A surgical R0 resection could be achieved in 43 patients, an R1 resection (minimal margin) in 7. Side effects and toxicity (common toxicity criteria) of RCT included grade I-II dysuria in 5 patients (10%), grade I-II diarrhea in 20 patients (40%), and severe diarrhea in 2 patients (4.0%). Grade I-II skin reaction was noticed in 22 patients (44.0%), severe skin reaction only in 1 patient. Regarding acute postoperative morbidity, abscess and fistula formation was noted in 8 patients (16.0%), with anastomosis leakage in 7 (14%). CONCLUSION: Preoperative radiotherapy appears to be a feasible therapeutic approach with moderate toxicity and the potential to induce down-staging. The data presented in this study confirm the preliminary reports on this neoadjuvant treatment.     

Internal motion of the vagina after hysterectomy for gynaecological cancer

Background and purpose

The purpose of this study was to investigate position changes of the vagina after hysterectomy for early stage cervical or endometrial cancer and their impact on CTV-PTV margins. We also studied their correlation with surrounding organ filling.

Materials and methods

Fifteen patients underwent T2-weighted MR scans before and weekly during the course of their EBRT. The vaginal CTVs and the surrounding organs were delineated. PTV margins were derived from the boundaries of the CTVs in the main directions and correlated with changes in the volumes of organs at risk. Additionally we investigated the impact of margin sizes on CTV coverage.

Results

The vaginal CTVs change their position in the pelvis during time with a maximum in anterior-posterior direction. The 95% confidence level was 2.3 cm into the anterior or posterior direction, 1.8 cm to left or right and 1.5 cm towards the cranial. With a homogenous 1.5 cm CTV-PTV margin ?5% inadequately covered vaginal CTV was seen in only 3.3% of the measurements. This increased to 20.6% with a margin of 1.0 cm. Concerning the impact of organ filling on vaginal position changes we found the only significant correlation with rectal volume and shift of the vagina towards anterior-posterior.

Conclusion

To accommodate the changes in the position of the vaginal CTV inhomogeneous PTV margins should be generated with the largest size in the anterior-posterior direction. The position shifts were only weakly related to the volume of the rectum and not at all to the volumes of other parts of the bowel and the bladder.     

Verification of guideline for gastric cancer treatment based on a questionnaire

We reported the results of a questionnaire survey of doctors and patients in relation to the guideline for gastric cancer treatment which was first published 3 years ago. The purpose of this questionnaire was to know whether the degree of recognition and availability of this guideline is satisfactory or not. The results were as follows. 1) The recognition and availability of the guideline among doctors proved satisfactory. 2) For patients who underwent gastrectomy, this guideline is still unfamiliar. Reconsideration of the guideline contents is needed in accord with the medical level from time to time. Moreover, patients must be more and more educated regarding the guideline.     

The Gynaecologic Leiden Questionnaire: psychometric properties of a self-report questionnaire of sexual function and vaginal changes for gynaecological cancer patients

Background: The aim of this study was to investigate the psychometric properties of the items concerning sexual functioning of the Gynaecologic Leiden Questionnaire (LQ), which consists of items for post operative morbidity for women with cancer. Methods: The total study sample consisted of 198 subjects: 66 patients treated for cervical cancer, 66 patients with sexual complaints and 66 subjects from the general population. Results: By means of factor analysis three subscales were derived: Female Sexual Complaints, Female Sexual Function and Female Orgasm. The reliability of the subscales appeared to be satisfactory. The scores on the three subscales differentiated well between the patients treated for cervical cancer, patients with sexual complaints and the subjects from the general population. Furthermore, the subscales were sensitive to changes within the patients treated for cervical cancer. The convergent and divergent construct validities of the LQ were investigated using other instruments measuring sexual functioning, sexual dissatisfaction, marital distress, general life distress and psychological distress. The LQ subscales were found to represent relatively independent constructs. Conclusion: The results support the reliability and psychometric validity of the LQ in the assessment of sexual functioning and vaginal changes in gynaecological cancer patients.

The potential of proton beam radiation therapy in prostate cancer, other urological cancers and gynaecological cancers

A group of Swedish oncologists and hospital physicists have estimated the number of patients in Sweden suitable for proton beam therapy. The estimations have been based on current statistics of tumour incidence, number of patients potentially eligible for radiation treatment, scientific support from clinical trials and model dose planning studies and knowledge of the dose-response relations of different tumours and normal tissues. In prostate cancer it is estimated that annually about 300 patients and in gynaecological cancer about 50 patients, are candidates for proton beam therapy. Owing to major uncertainties, it has not been possible to give an estimate of the number of potential patients with urinary bladder cancer.     

Physical and psychological morbidity after axillary lymph node dissection for breast cancer.

PURPOSE: Alternatives to axillary lymph node dissection (ALND) are being developed amid controversy surrounding the therapeutic benefit and overall utility of this routine surgical procedure. Although potential negative side effects associated with ALND are known, we set out to examine whether these side effects contribute significantly to patient reports of quality of life and mental health. PATIENTS AND METHODS: We surveyed 222 women who had received an ALND as part of breast cancer surgery. All women underwent a physical therapy assessment of range of arm/shoulder motion and completed the Modified Post-operative Pain Questionnaire, the Pain Disability Index, the McGill Pain Questionnaire (short form), the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, and the Mental Health Inventory. RESULTS: Seventy-two percent of the women experienced arm/shoulder pain, weakness, or numbness in the week before the interview, and range of motion of the affected arm/shoulder was impaired in 73% of the women. Severity of pain was reported to be low to moderate, and younger patients experienced greater pain than older patients. Pain severity correlated positively with the number of lymph nodes removed and receipt of chemotherapy and was not significantly related to length of time since surgery or receipt of radiation therapy. Generally high levels of cancer-specific quality of life and mental health were reported. Quality of life was significantly predicted by the McGill Pain Questionnaire, and mental health was significantly predicted by the Pain Disability Index and the physical therapy assessment. CONCLUSION: Surgery-related symptoms after ALND persist for a majority of women with breast cancer and are not significantly related to time since surgery or receipt of radiation therapy. These symptoms and associated disability are significantly predictive of cancer-specific quality of life and mental health.     

Psychiatric morbidity in patients with advanced cancer of the breast: prevalence measured by two self-rating questionnaires

Two hundred and twenty-two women with advanced cancer of the breast were asked to complete two previously validated self-assessment questionnaires (Hospital Anxiety and Depression Scale (HADS) and the Rotterdam Symptom Checklist (RSCL) in order to determine the prevalence and persistence of affective disorders in this group of patients. Fifty-six (27%) of 211 women who completed the HADS and 33 (22%) of 204 who completed the RSCL rated as probable cases of an anxiety state and/or depressive illness. One hundred and fifty-five patients completed the questionnaires again 1-3 months later. Twenty-one (13%) were persistently anxious or depressed as judged by the HADS compared with 14 (10%) on the RSCL. When both questionnaires were considered together, approximately one third of patients had scores suggestive of an affective disorder and in one third of these it was persistent. Only 30 patients (43% of cases) were detected as 'cases' by both questionnaires and this finding warrants further investigation.     

Arm morbidity after breast-conserving therapy for breast cancer

This study reports on 110 consecutive patients, mean age 59 years, operated on for partial mastectomy and axillary dissection. Radiotherapy of 50 Gy was administered to 75 of the patients. Most tumours were T1 tumours and all patients were NO. Lymphoedema is defined as an increase in arm volume > 10% and impaired shoulder mobility as an impairment of 15 degrees compared with the preoperative value. After operation, 21 patients developed lymphoedema, 17 in the radiotherapy group and 4 in the group without radiotherapy; 49% of the patients had reduced shoulder mobility, and of these, 57% were in the radiotherapy group and 30% in the group without radiotherapy. We found a good correlation between the number of patients stating arm swelling and patients with registered lymphoedema. There were fewer patients stating limitation of movement than patients with registered impaired mobility; 31% of patients were still perceiving some pain five years after the operation. We conclude, that breast-conserving therapy in breast cancer is afflicted with a significant arm morbidity that persists for several years after surgery.     

Chemotherapy and radiotherapy for urological cancer

Prostate cancer, bladder cancer, renal cancer and testicular cancer are common among urological cancers. The treatment strategy for testicular cancer using chemotherapy has been well established and has been shown to be successful. Chemotherapy and radiotherapy play important roles in multidisciplinary therapy for bladder cancer. Radiotherapy is often used as a radical treatment that is practically equivalent to surgery for prostate cancer. In addition, radiotherapy is useful in cases of bone or brain metastases. In the field of chemotherapy, the development of new agents that would make breakthroughs similar to that of cisplatin is awaited. Taxanes and gemcitabine are good candidates. In the field of radiotherapy, 3D conformal radiation therapy (CRT), which has excellent beam distribution, has recently come into wide use. Moreover, brachytherapy and proton and ion beam therapy are expected to prove useful in prostate cancer therapy.     

Chronic arm morbidity after curative breast cancer treatment: prevalence and impact on quality of life.

PURPOSE: To determine the prevalence of and contributing factors for chronic arm morbidity including lymphedema in breast cancer patients after treatment and to assess the impact of arm morbidity on quality of life (QOL). PATIENTS AND METHODS: A four-question screening questionnaire was developed and mailed to a random sample of 744 breast cancer patients treated curatively in two cancer centers from 1993 to 1997. Patients were without recurrence and at least 2 years from diagnosis. Respondents were classified as with or without arm-related symptoms on the basis of the survey. Stratified random samples from each group were then invited for a detailed assessment of their symptoms and signs, including the presence of lymphedema. Their QOL was assessed by the European Organization for Research and Treatment of Cancer QOL Questionnaire C-30 and by a detailed arm problem questionnaire that assessed various aspects of daily arm functioning. RESULTS: Approximately half of all screened patients were symptomatic and 12.5% of all assessed patients had lymphedema. Axillary dissection (AD) and axillary radiotherapy (RT) after dissection were statistically significantly related to the occurrence of arm symptoms (odds ratio for AD = 3.3, P <.001; odds ratio for RT = 3.1, P <.001). Symptomatic patients and patients with lymphedema both had impaired QOL compared with asymptomatic patients. CONCLUSION: Treatment for breast cancer is associated with considerable arm morbidity, which has a negative impact on QOL. Arm morbidity should be carefully monitored in future studies involving local treatment modalities for breast cancer.     

Urinary diversion and morbidity after radical cystectomy for bladder cancer

BACKGROUND:

The rate of continent urinary diversion after radical cystectomy for bladder cancer varies by patient and provider characteristics. Demonstration of equivalent complication rates, independent of diversion type, may decrease provider reluctance to perform continent reconstructions. The authors sought to determine whether continent reconstructions confer increased complication rates after radical cystectomy.

METHODS:

From the Nationwide Inpatient Sample, the authors used International Classification of Disease (ICD‐9) codes to identify subjects who underwent radical cystectomy for bladder cancer during 2001‐2005. They determined acute postoperative medical and surgical complications from ICD‐9 codes and compared complication rates by reconstruction type using the nearest neighbor propensity score matching method and multivariate logistic regression models.

RESULTS:

Adjusting for case‐mix differences between reconstructive groups, continent diversions conferred a lower risk of medical, surgical, and disposition‐related complications that was statistically significant for bowel (3.1% lower risk; 95% confidence interval [95% CI], ?6.8% to ?0.1%), urinary (1.2% lower risk; 95% CI, ?2.3%, to ?0.4%), and other surgical complications (3.0% lower risk; 95% CI, ?6.2% to ?0.4%), and discharge other than home (8.2% lower risk; 95% CI, ?12.1% to ?4.6%) compared with ileal conduit subjects. Older age and certain comorbid conditions, including congestive heart failure and preoperative weight loss, were associated with significantly increased odds of postoperative medical and surgical complications in all subjects.

CONCLUSIONS:

Mode of urinary diversion after radical cystectomy for bladder cancer is not associated with increased risk of immediate postoperative complications. These results may encourage broader consideration of continent urinary diversion without concern for increased complication rates. Cancer 2010. © 2010 American Cancer Society.     

Late morbidity after treatment of breast cancer in relation to daily activities and quality of life: a systematic review.

AIMS: Breast cancer treatment may result in long-term upper limb morbidity: reduced range of motion of the shoulder, muscle weakness of the arm and hand, lymph edema, pain and numbness. Relationship of this late morbidity with activities of daily life (ADL) and quality of life (QOL) is infrequently described and the strength of this relationship is not clear. METHODS: A systematic review was performed to evaluate the results of studies, analyzing late morbidity of breast cancer treatment in relationship with ADL and/or QOL. A literature search over the last 20 years (1980-2000) was performed in the databases MEDLINE, EMBASE, PSYCHLIT and CANCERLIT. Methodological quality of selected articles was assessed and additional, aspects of treatment related late morbidity and the relationship to ADL and/or QOL were summarized. RESULTS: From the 1642 yielded articles 15 fulfilled our primary selection criteria. Only six articles could be selected due to the inappropriate methodological quality. There was high variation in prevalence of pain (12-51%), impairments in range of motion (2-51%), edema (6-43%) and decreased muscle strength (17-33%). Four articles reported significant relationships between late morbidity of the upper limb and perceived disabilities in ADL/QOL. The strength of these relationships was rather low. CONCLUSIONS: Few studies investigated the relationship between late morbidity of the upper limb after treatment of early breast cancer and ADL/QOL. Significant relationship between late morbidity and restrictions of daily activities and poorer QOL was reported, however, the strength of this relationship was rather low.
