Ten-year trend analysis of breast cancer, oncoplastic, and reconstructive breast surgery in a single institution (2010-2019), what has not changed?

PURPOSE

There has been a UK national directive to ensure that patients are offered reconstructive surgical options. We aimed to assess any change in oncoplastic practice over a 10-year period.

METHODS

The surgical management of 7019 breast cancers was retrospectively assessed at Nightingale Breast Centre, Manchester University UK, from 2010 to 2019. The procedures were categorised into breast conservative surgery (BCS) and mastectomy ± immediate reconstruction. The data were analysed using inclusion and exclusion criteria.

RESULTS

The overall rates of BCS and mastectomy were 60.1% and 39.9% respectively. No statistically significant change in the overall rates of BCS or mastectomy was observed over the last decade (p = 0.08). The rate of simple wide local excision (WLE) decreased from 98.7% to 89.3% (p < 0.001), whilst the rate of therapeutic mammoplasty (TM) increased from 1.3% to 8% (p < 0.01). The rate of chest wall perforator flaps (CWPF) changed from zero to account for 2.7% of all BCS by 2019. The overall rate of immediate breast reconstruction (IBR) did not significantly change over the study period, but it consistently remained above the national average of 27%. The rate of implant-based IBR increased from 61.3% to 76.5% (p = 0.012), whilst the rate of Latissimus Dorsi (LD) reconstruction decreased from 26.7% to 5.1% (p < 0.05). Additionally, the rate of nipple-sparing mastectomy significantly increased from 5.2% to 24%.

CONCLUSION

No significant changes in the overall rates of BCS was observed, the rates of advanced breast conservation techniques, nipple-sparing mastectomy, and implant-based IBR all have increased, whilst the use of LD reconstruction decreased.

Cigarettes and waterpipe smoking among medical students in Syria: a cross-sectional study

OBJECTIVES

To investigate tobacco use, beliefs and attitudes among medical students in Syria.

METHODS

A cross-sectional study of a random sample of 570 medical students (first and fifth year) registered at the Damascus University Faculty of Medicine in 2006-2007. We used a self-administered questionnaire for demo-graphic information, smoking behaviour (cigarette, waterpipe), family and peer smoking, attitudes and beliefs about smoking and future role in advising patients to quit smoking.

RESULTS

The overall prevalence of tobacco use was 10.9% for cigarettes (15.8% men, 3.3% women), 23.5% for waterpipe (30.3% men, 13.4% women) and 7.3% for both (10.1% men, 3.1% women). Both smoking methods were more popular among the fifth year students (15.4% and 27%) compared to their younger counterparts (6.6% and 19.7%). Regular smoking patterns predominated for cigarettes (62%), while occasional use patterns predominated for waterpipes (83%). More than two thirds of students (69%) thought they might not address or would have difficulty addressing smoking in their future patients.

CONCLUSION

The level of tobacco use among Syrian medical students is alarming and highlights the rapidly changing patterns of waterpipe use, especially among female students. Medical schools should work harder to tackle this phenomenon and address it more efficiently in their curricula.

Multifocal osteosarcoma: an unusual presentation

PURPOSE

Report the unusual presentation, clinical course, and cytogenetic abnormalities in a child with multifocal osteosarcoma.

PATIENTS AND METHODS

A 10-year-old boy had multifocal osteosarcoma involving the entire skeleton, pleura, bone marrow, and lungs. He had marked anemia, thrombocytopenia, and severe hypocalcemia at diagnosis.

RESULTS

Despite aggressive chemotherapy, he died from progressive disease 1 month after diagnosis. Cytogenetic analysis of tumor cells within the pleural fluid showed multiple chromosomal abnormalities with amplification of the c-myc oncogene.

CONCLUSION

Multifocal osteosarcoma should be considered in the differential diagnosis of a child with pancytopenia and multiple bone lesions. Amplification of the c-myc oncogene may have had a significant role in the pathogenesis, etiology, and rapid progression of this patient's multifocal disease. Additional studies will be needed to determine the biologic significance of c-myc amplification in multifocal osteosarcoma.

Final attained height in patients successfully treated for childhood acute lymphoblastic leukemia

We evaluated final adult height in 109 patients treated for childhood acute lymphoblastic leukemia on two multiarm Pediatric Oncology Group protocols between 1974 and 1981. Fifty-one patients received 2400 cGy cranial irradiation (XRT), and 58 patients received no XRT. All patients had no central nervous system involvement at diagnosis, achieved and maintained a complete response, entered puberty spontaneously, and had achieved final height. Height data were converted to standardized deviation scores. Mean age at diagnosis was 7.8 +/- 4.2 years. Distribution of heights at diagnosis was similar to that of the U.S. population. Relative to gender-specific heights for the population, female subjects in this study had lower attained heights than male subjects (p = 0.03). There was a monotonic trend of patients treated at an earlier age to have a reduction in final height (p = 0.057). Cranial irradiation was strongly associated with final height (mean standardized deviation score with XRT = -1.04 and without XRT = -0.14; p < 0.001). Final height was not associated with age at diagnosis, prognostic risk group, or Pediatric Oncology Group protocol. By multivariate analysis, only XRT and XRT x age were significantly associated with final height (p < 0.001 and p = 0.002, respectively). There was no significant gender effect. We conclude that XRT is significantly associated with reduced final adult height after treatment for childhood acute lymphoblastic leukemia. For survivors, therapy devoid of XRT does not appear to affect final height.
