Male breast cancer: a nation-wide population-based comparison with female breast cancer.

OBJECTIVE: Describe prognostic parameters of Danish male breast cancer patients (MBCP) diagnosed from 1980-2009. Determine all-cause mortality compared to the general male population and analyze survival/mortality compared with Danish female breast cancer patients (FBCP) in the same period. MATERIAL AND METHODS: The MBCP cohort was defined from three national registers. Data was extracted from medical journals. Data for FBCP is from the DBCG database. Overall survival (OS) was quantified by Kaplan-Meier estimates. Standardized mortality ratios (SMRs) were calculated based on mortality rate among patients relative to the mortality rate in the general population. The association between SMR and risk factors were analyzed in univariate and multivariable Poisson regression models. Separate models for each gender were used for the analyses. RESULTS: We found a marked difference in OS for the two genders. For the total population of MBCP, 5- and 10-year survivals were 55.1% and 31.7%, respectively. For FBCP, the corresponding figures were 76.8% and 59.3%. Median age at diagnosis for FBCP was 61 years and 70 years for MBCP. By applying SMR, the difference in mortality between genders equalized and showed pronounced age-dependency. For males <40 years, SMR was 9.43 and for females 19.56 compared to SMR for males 80 + years (0.95) and females 80 + years (0.89). During the period 1980-2009, the risk of dying gradually decreased for FBCP (p < .0001). The risk 1980-1984 was 35% higher than 2005-2009 (RR 1.35). Although the risk of dying for MBCP was also lowest in 2005-2009, there was no clear tendency (p = .1439). The risk was highest in 1990-1994 (RR =2.48). CONCLUSION: We found better OS for FBCP than for MBCP. But SMR showed similar mortality rate for the two genders, except for very young FBCP, who had higher SMR. Furthermore, significantly improved survival over time for FBCP was observed, with no clear tendency for MBCP.

Good health-related quality-of-life and high patient-reported satisfaction after delayed breast reconstruction with pedicled flaps from the back.

BACKGROUND: This paper presents the results of a randomized controlled trial (RCT) that focus on health-related quality-of-life (QoL) and patient-reported satisfaction following breast reconstruction with pedicled flaps from the back. MATERIALS & METHODS: We included women for unilateral delayed breast reconstruction. Patients were randomized to reconstruction by either a latissimus dorsi (LD) flap or a thoracodorsal artery perforator (TAP) flap. Assessment of QoL and patient satisfaction was made using two different patient-reported outcome measures (PROMs): The EORTC QLQ-30 and the Breast-Q questionnaire for post-mastectomy breast reconstruction. RESULTS: A total of 50 women were enrolled over a two-year period and allocated to reconstruction. Forty patients completed both surgery and follow-up and were included in the analysis - 18 in the LD group and 22 in the TAP group. The EORTC QLQ-30 was administered at the baseline and at one-year follow-up. There was no significant effect of introducing the TAP flap on either the summary score, the global QoL-score or the financial impact-score when compared to the LD flap. The Breast-Q questionnaire was administered only at one-year follow-up. There was no significant difference between the two groups for the scores for satisfaction with the reconstructed breast, the overall outcome and QoL related to psycho-social, sexual and physical well-being. CONCLUSION: Women from both groups report high satisfaction and QoL following the reconstruction. The quality of the dataset and the study design are, however, insufficient to rule out any existing difference. A larger cohort, longer follow-up and different design are warranted to assess the true clinical significance these reconstructions might have on satisfaction and QoL.

Shoulder-related donor site morbidity after delayed breast reconstruction with pedicled flaps from the back: An open label randomized controlled clinical trial.

BACKGROUND: This randomized controlled trial (RCT) investigates differences in shoulder-related morbidity after delayed breast reconstruction by either a latissimus dorsi (LD) flap or a thoracodorsal artery perforater (TAP) flap. MATERIAL AND METHODS: In accordance with the CONSORT guidelines, we included women for unilateral delayed breast reconstruction. Patients were randomized to reconstruction by either of the two flaps. Shoulder-function was assessed at baseline and at 3, 6 and 12 months after surgery. The primary endpoint was patient-reported shoulder-related pain. A further objective assessment by the Constant Shoulder Score (CSS) was included as secondary endpoints. RESULTS: A total of 50 women were enrolled over a two-year period and allocated to reconstruction, with 25 patients in each group. Patient-reported shoulder-related pain was significantly lower in the TAP group at 12 months after surgery when adjusting for pain at baseline: OR = 0.05 95%CI(0.005-0.51), p-value = 0.011. The estimated effect on the total CSS at 12 months, when applying the TAP flap instead of the LD flap and adjusting for the baseline score, was 6.2 points with 95%CI(0.5-12.0), p-value 0.033. The TAP flap seems to have a statistically significant positive effect on pain and activity in daily life (ADL), while there were no significant effect on range of motion and strength after one year. CONCLUSION: Patient reconstructed by the TAP flap are less likely to experience shoulder-related pain and have a better shoulder-function one year after the reconstruction. Harvest of the LD flap carries a higher risk of shoulder-function impairment, chronic pain and reduced ADL.

Shoulder-related donor site morbidity and patient-reported satisfaction after delayed breast reconstruction with pedicled flaps from the back: A comparative analysis.

BACKGROUND: We report a study evaluating and comparing shoulder-related morbidity associated with delayed breast reconstruction using either the conventional latissimus dorsi (LD) flap or the thoracodorsal artery perforator (TAP) flap. MATERIAL & METHODS: We conducted a retrospective cohort study of women over 18 years of age who had a unilateral, delayed breast reconstruction by either an LD or TAP flap at one center over a 56-month period. Shoulder function was assessed using the Constant Shoulder Score (CSS), which evaluated pain, activity of daily life (ADL), range of motion (ROM), and strength. A number of secondary outcomes were also examined. RESULTS: Forty-nine women were included. Demographic and breast treatment data were comparable between the groups. The mean total CSS score for the reconstructed side of the TAP flap was statistically significantly better than that of the LD flap, with a difference of 10.9 points (95% confidence interval [CI] = 2.6-19.2, p-value 0.01). The mean total CSS score for the nonreconstructed side was not statistically significant between groups, with a difference of 0.1 points (95% CI = -6.1-6.2, p-value 0.98). The subscore analysis revealed that women reconstructed using the TAP flap had a difference of 3.2 points for pain (p-value 0.003) and 5.5 points for ROM (p-value 0.011). The factors ADL and strength were of equal magnitude in both groups. CONCLUSIONS: Patients who undergo delayed breast reconstruction by the TAP flap seem less prone to suffer from postoperative pain and restricted ROM, thereby suggesting that this flap should be considered an advantageous alternative to the conventional LD flap. A randomized clinical trial is warranted to provide sufficient evidence to this statement.

Diagnostic interval and mortality in colorectal cancer: U-shaped association demonstrated for three different datasets.

OBJECTIVE: To test the theory of a U-shaped association between time from the first presentation of symptoms in primary care to the diagnosis (the diagnostic interval) and mortality after diagnosis of colorectal cancer (CRC). STUDY DESIGN AND SETTING: Three population-based studies in Denmark and the United Kingdom using data from general practitioner's questionnaires, interviewer-administered patient questionnaires, and primary care records, respectively. RESULTS: Despite variations in the potential selection and information bias when using different methods of identifying the date of first presentation, the association between the length of the diagnostic interval and 5-year mortality rate after the diagnosis of CRC was the same for all three types of data: displaying a U-shaped association with decreasing and subsequently increasing mortality with longer diagnostic intervals. CONCLUSION: Unknown confounding and in particular confounding by indication is likely to explain the counterintuitive findings of higher mortality among patients with very short diagnostic intervals, but cannot explain the increasing mortality with longer diagnostic intervals. The results support the theory that longer diagnostic intervals cause higher mortality in patients with CRC.
