Investigating sexual health after breast cancer by longitudinal assessment of patient-reported outcomes.

BACKGROUND: Sexual concerns are a major unaddressed need among survivors of breast cancer (BC) with significant negative effects on quality of life. We longitudinally analyzed sexual health over time, using patient-reported outcomes. METHODS: Patients with stage I-III BC prospectively included from the CANcer TOxicity cohort (CANTO) provided data at diagnosis, then 1, 2, and 4 years afterward. Sexual concerns outcomes included poor body image (score ≤91/100), poor sexual functioning (≤16/100), poor sexual enjoyment (≤66/100), and sexual inactivity (EORTC QLQ-B23). Multivariate generalized estimating equation models assessed associations with sexual concerns after diagnosis, adjusting for age, sociodemographic, tumor, treatment, and clinical characteristics. RESULTS: Nearly 78.1% among 7895 patients reported at least one sexual concern between diagnosis and 4 years' follow-up. Over time, the proportion of patients reporting sexual concerns either increased or remained constant with diagnosis. Less than half (46%, range 11.4-57) of the patients with sexual concerns reported the use of supportive care strategies, including gynecological or psychological consultations (range 11.4-57.4). Factors consistently associated with sexual concerns up to 4 years after diagnosis included already reporting the same concern at diagnosis [odds ratio (OR)poor body image 3.48 [95% confidence interval (CI) 3.11-3.89]; ORsexual inactivity 9.94 (95% CI 8.84-11.18), ORpoor sexual function 9.75 (95% CI 8.67-10.95), ORpoorsexual enjoyment 3.96 (95% CI 3.34-4.69)], endocrine therapy use [ORpoor body image 1.15 (95% CI 1.01-1.31); ORsexual inactivity 1.19 (95% CI 1.02-1.39), ORpoor sexual function 1.17 (95% CI 1.01-1.37), ORpoor sexual enjoyment 1.23 (95% CI 1.00-1.53)], and depression [ORpoor body image 2.00 (95% CI 1.72-2.34); ORsexual inactivity 1.66 (95% CI 1.40-1.97), ORpoor sexual function 1.69 (95% CI 1.43-2.00), ORpoor sexual enjoyment 1.94 (95% CI 1.50-2.51)]. Outcome-specific associations were also identified. CONCLUSIONS: Sexual concerns seem frequent, persistent, and insufficiently addressed. Pretreatment concerns, endocrine therapy, and emotional distress are commonly associated factors. A proactive evaluation of sexual health across the care continuum is needed, to promptly identify patients suitable for multidisciplinary counseling, referral, and supportive interventions.

Factors associated with enrolment in clinical trials among women with early-stage breast cancer.

BACKGROUND: Clinical trials allow development of innovative treatments and ameliorate the quality of clinical care in oncology. Data show that only a minority of patients are enrolled in clinical trials. We assessed enrolment in clinical trials and its correlates among women with early breast cancer. METHODS: We included 9516 patients with stage I-III breast cancer from the multicenter, prospective CANTO study (NCT01993498), followed-up until year 4 (Y4) post-diagnosis. We assessed factors associated with enrolment using multivariable logistic regression. In exploratory, propensity score matched analyses, we used multiple linear regression to evaluate the relationship of enrolment in clinical trials with the European Organisation for Research and Treatment of Cancer Quality Of Life (QoL) questionnaire (EORTC QLQ-C30) Summary Score and described clinical outcomes (distant disease event, invasive disease event, and death by any cause) according to enrolment. RESULTS: Overall, 1716 patients (18%) were enrolled in a clinical trial until Y4 post-diagnosis of breast cancer. Socioeconomic factors were not associated with enrolment. Centres of intermediate volume were most likely to enrol patients in clinical trials [versus low volume, odds ratio 1.45 (95% confidence interval (CI) 1.08-1.95), P = 0.0124]. Among 2118 propensity score matched patients, enrolment was associated with better QoL at Y4 (adjusted mean difference versus not enrolled 1.37, 95% CI 0.03-2.71, P = 0.0458), and clinical outcomes (enrolled versus not enrolled, distant disease event 7.3% versus 10.1%, P = 0.0206; invasive disease event 8.2% versus 10.5%, P = 0.0732; death by any cause 2.8% versus 3.7%, P = 0.2707). CONCLUSIONS: In this large study, one in five patients enrolled on a clinical trial until Y4 after diagnosis of early breast cancer. Geographical and centre-related factors were significantly associated with enrolment in clinical trials. Inclusion in clinical trials seemed associated with improved QoL and clinical outcomes. Access to innovation for early-stage breast cancer patients should be encouraged and facilitated by overcoming organizational and geographical barriers to recruitment.

Gallium scanning in the 'new' tuberculosis.

PURPOSE: To evaluate the findings and usefulness of Ga-67 scanning in recent cases of tuberculosis (TB). MATERIALS AND METHODS: The authors reviewed chest x-ray films and Ga-67 citrate scans of 52 patients with culture-confirmed infection caused by Mycobacterium tuberculosis treated after 1988. RESULTS: Ga-67 scans were positive in every case, delineating upper lobe lung lesions in 6 patients, diffuse involvement or lower lobe disease in 34 patients, and intrathoracic adenopathy in 15 patients. Pulmonary parenchymal lesions were not detected on x-ray films in 3 patients, and nodal lesions were not apparent in 3 patients. In addition, in 6 patients cervical adenopathy was detected by Ga-67 scintigraphy; 4 underwent biopsy with culture confirmation. CONCLUSIONS: Ga-67 scanning is more sensitive than routine chest radiography for detection of both TB parenchymal lung involvement and adenopathy. Ga-67 imaging facilitates the choice of biopsy sites by identifying accessible peripheral nodes. Typical patterns in recent cases of TB differ significantly from the upper lobe predilection of classical TB.

Chloride ion concentration in vaginal discharge and urine during puberty.

In 27 prepubertal-pubertal girls the chloride ion concentration in vaginal discharge and urine was estimated four times during the menstrual cycle by means of a direct new micromethod using a Cl-selective electrode. In pubertal girls the chloride content showed changes both in vaginal discharge and in urine; the latter changed practically parallel with the vaginal value. A sharp rise in chloride content characteristic of normal ovulation was observed in 5 patients free from hormonal disturbances, while there were significant differences during ovulation 5 times and in the premenstrual phase 6 times in the girls with hormonal disturbances.

Tissue pH in the assessment of ischaemic muscle damage.

Measurement in vivo of the pH of superficial muscles of dogs was found suitable for the assessment of the severity of ischaemic muscle damage and for the detection of irreversible lesions.
