Recurrence of high-grade cervical abnormalities following conservative management of cervical intraepithelial neoplasia grade 2

OBJECTIVE Conservative management of cervical intraepithelial neoplasia (CIN) grade 2 in women younger than 25 years may reduce overtreatment. However, long-term efficacy remains uncertain. This retrospective cohort study aimed to determine the rate of recurrence of high-grade abnormalities among young women with a history of CIN 2 that spontaneously regressed within 2 years and compare this with the rate of high-grade abnormality in similar women with an initial diagnosis of CIN 1. STUDY DESIGN We identified all women aged younger than 25 years who were diagnosed with CIN 1 or CIN 2 between January 2005 and August 2009 within 2 colposcopy units. Follow-up data from the National Cervical Screening Programme were obtained to identify those women who developed recurrent high-grade lesions before October 2012. Comparisons were made using Cox proportional hazards regression. RESULTS A total of 683 women were included: 106 with CIN 2 that spontaneously regressed, 299 with treated CIN 2, and 278 with conservatively managed CIN 1. Median follow-up was 4 years. There was no significant difference in the risk of development of high-grade abnormalities after 2 years between the spontaneously regressing CIN 2 and CIN 1 groups (P = .83). Women with treated CIN 2 had a significantly lower risk of recurrence than women with untreated CIN 2 (P = .01). CONCLUSION CIN 2 that has spontaneously regressed appears to behave as a low-grade lesion. This study contributes to the growing body of evidence that careful observation of CIN 2 is an efficacious and appropriate initial management option for women aged younger than 25 years at diagnosis.

Low level laser therapy (Photobiomodulation therapy) for breast cancer-related lymphedema: a systematic review

BackgroundBreast cancer related lymphedema (BCRL) is a prevalent complication secondary to cancer treatments which significantly impacts the physical and psychological health of breast cancer survivors. Previous research shows increasing use of low level laser therapy (LLLT), now commonly referred to as photobiomodulation (PBM) therapy, for BCRL. This systematic review evaluated the effectiveness of LLLT (PBM) in the management of BCRL.MethodsClinical trials were searched in PubMed, AMED, Web of Science, and China National Knowledge Infrastructure up to November 2016. Two reviewers independently assessed the methodological quality and adequacy of LLLT (PBM) in these clinical trials. Primary outcome measures were limb circumference/volume, and secondary outcomes included pain intensity and range of motion. Because data were clinically heterogeneous, best evidence synthesis was performed.ResultsEleven clinical trials were identified, of which seven randomized controlled trials (RCTs) were chosen for analysis. Overall, the methodological quality of included RCTs was high, whereas the reporting of treatment parameters was poor. Results indicated that there is strong evidence (three high quality trials) showing LLLT (PBM) was more effective than sham treatment for limb circumference/volume reduction at a short-term follow-up. There is moderate evidence (one high quality trial) indicating that LLLT (PBM) was more effective than sham laser for short-term pain relief, and limited evidence (one low quality trial) that LLLT (PBM) was more effective than no treatment for decreasing limb swelling at short-term follow-up.ConclusionsBased upon the current systematic review, LLLT (PBM) may be considered an effective treatment approach for women with BCRL. Due to the limited numbers of published trials available, there is a clear need for well-designed high-quality trials in this area. The optimal treatment parameters for clinical application have yet to be elucidated.

Observational Management of CIN 2 in Young Women: A Prospective Multicenter Trial.

Objectives We present the rationale and methods for PRINCess—a multicenter prospective trial—which aims to determine outcome and predictors of regression in a large cohort of women younger than 25 years with cervical intraepithelial neoplasia grade 2 (CIN 2) undergoing observational management. Materials and Methods Six hundred women younger than 25 years with newly diagnosed biopsy-proven CIN 2 are being recruited to observational management (i.e., repeat colposcopy, cytology, and cervical biopsy every 6 months for 2 years). Five hundred fifty-two women from throughout New Zealand and 1 site in Australia have been recruited so far. Measures include histology, cytology, human papillomavirus genotyping, and immunohistochemical staining. Women who develop CIN 3 will be treated with large loop excision of the transformation zone. The primary outcomes are rates of clinical regression of CIN 2 (i.e., 2 consecutive colposcopy follow-ups showing CIN 1 or normal), loss to follow-up, and progression to invasion. Conclusions The optimal treatment for young women with a diagnosis of CIN 2 is controversial. Although many undergo surgical treatment, observational management is increasingly recommended. However, there is little evidence from large clinical trials of the safety and practicality of observational management of young women with CIN 2. When completed, we will have adequate evidence by which to counsel women regarding their likely outcomes and to offer advice on clinical follow-up protocols.

Low level laser therapy in the management of breast cancer-related lymphedema: protocol for a randomized controlled feasibility trial

Abstract Background: Breast cancer-related lymphedema (BCRL) is a prevalent long-term condition secondary to cancer treatment. BCRL impacts physical function, psychological health, and quality of life for patients who have survived breast cancer. Objectives: This study will assess the feasibility of a fully-powered randomized controlled trial investigating the effectiveness of low level laser therapy (LLLT), also known as photobiomodulation (PBM) therapy, as an adjunct treatment for managing BCRL. Methods: This study will be a pragmatic two-armed randomized controlled feasibility trial. Twenty female participants being treated for BCRL at the Dunedin Hospital, New Zealand, will be recruited over a 6-month window. Subject to informed consent, participants will be offered LLLT (PBM) in addition to their regular treatment for BCRL. Twelve treatments with laser therapy will continue for 6 weeks (twice weekly). Feasibility outcomes (recruitment rate, randomization rate, participant’s adherence to the LLLT (PBM) treatment protocol, and participant retention rates) will be collected during the recruitment and intervention period. Participant satisfaction will be collected on completion of treatment intervention. Safety outcomes of LLLT (PBM) will be collected at each treatment visit. Clinical outcome measures (limb circumference, participant’s perceived symptoms, psychological impacts, and activity disability) will be assessed at baseline, 6 and 12 weeks post-randomization. Conclusions: Results of this feasibility trial will inform the design and implementation of a future definitive randomized controlled trial, which will investigate the effectiveness of LLLT (PBM) for women with BCRL.

Low level laser therapy for the management of breast cancer-related lymphedema: A randomized controlled feasibility study: LASER THERAPY FOR BREAST CANCER RELATED-LYMPHEDEMA

This study aimed to determine the feasibility of conducting a full scale randomized controlled trial investigating the effectiveness of low level laser therapy (LLLT), also known as photobiomodulation (PBM) therapy, used in addition to conventional therapy, for managing breast cancer related lymphedema (BCRL).

Low level laser therapy (photobiomodulation) for the management of breast cancer-related lymphedema: an update

Breast cancer related lymphedema (BCRL) is prevalent among breast cancer survivors, and may be painful and disfiguring with associated psychological impact. Previous research shows increasing use of low level laser therapy (LLLT), now commonly referred to as photobiomodulation (PBM) therapy for managing BCRL, in countries including the United States and Australia. However, conclusions were limited by the paucity, heterogeneity, and poor quality of previous studies. LLLT (PBM) has been barely used in clinical practice in New Zealand, and no clinical studies on LLLT (PBM) for BCRL have been conducted in this country. In order to promote this potentially useful treatment modality for BCRL patients, the Laser Lymphedema Trial Team at the University of Otago conducted a program to assess the effectiveness of LLLT (PBM) in management of BCRL. The program comprises three phases including a systematic review (completed), a feasibility study (completed), and a full-scale randomized controlled trial (proposed). This current paper provides an update on the program. Based upon the systematic review, LLLT (PBM) is considered a potentially effective treatment approach for women with BCRL; the review also indicated the need for further research including exploration of the relevance of dosage and other LLLT (PBM) parameters. The feasibility study demonstrated that it is feasible to conduct a fully powered RCT to definitively test the effectiveness of the additional use of LLLT (PBM) in the management of BCRL, and 114 participants will be needed at baseline in the main study. Currently, the full-scale RCT is under preparation.

Caesarean scar pregnancy at 19 weeks gestation

Due to the increased numbers of caesarean sections in the last decade, women with a caesarean section scar in pregnancy are becoming more commonly diagnosed using ultrasound. One of the rare but more severe complications of this is an implantation of the pregnancy in the caesarean section scar.
