Inguino-femoral lymph node metastasis in vulvar cancer accounts for increased risk of recurrence and 50% decrease in survival. Adjuvant radiotherapy for single positive IFLN vulvar cancer has persisted as a controversial topic since the publication of GOG 37. Retrospective data from Germany indicates that there is no difference in survival for patients with single node positive vulvar cancer treated with adjuvant radiotherapy or observation. Radical surgery, even with SLNB, followed by radiotherapy can lead to devastating and difficult-to-treat complications including wound infections, lymphedema, pain, and bone fractures. Considering these complications, overall quality of life, and the limited data demonstrating improved survival benefit, it would be beneficial to withhold adjuvant radiotherapy for patients with single-positive IFLN vulvar cancer. Further studies aimed at understanding the molecular landscape and investigating targeted and immunotherapy for vulvar cancer will aid in the treatment of this complex cancer.
During the SARS-CoV-2 virus pandemic, University Hospital Birmingham NHS Trust Oncology Department incorporated the ultrahypofractionated regime of 26Gy/5 fractions alongside the moderate hypofractionated regime of 40Gy/15 fractions as part of local adjuvant breast radiotherapy treatment (RT) for eligible patients. We conducted a local study to assess the real-life experience of patients undergoing ultrahypofractionated schedule to compare feasibility and toxicity to the fast-forward trial during the COVID − 19 pandemic.
Methods:
A single institution, retrospective, qualitative study. Patients included had early-stage breast cancer and received adjuvant radiotherapy between 23 March 2020 and 31 May 2020, a total of 211 patients. Inclusion was irrespective of any other neoadjuvant/adjuvant treatments. Data were collected retrospectively for treatment dose, boost dose and toxicity.
Results:
Of the total 211 patients, 85 were treated with 26Gy in 5# and 19 patients received a boost as per the fast-forward protocol. Of these 85 patients, 15·9% did not report any skin toxicity post-treatment. 63·5% of patients reported RTOG Grade 1, 15·9% had RTOG Grade 2, and 1·6% reported RTOG Grade 3 skin toxicity. 3·2% of the patients could not be contacted for follow-up. Of the 19 patients who received a breast boost, 10·53% reported no skin changes. 78·9% reported Grade 1 skin toxicity. Both Grades 2a and 2b skin toxicity were reported by 5·26% each. The patient demographics and tumour characteristics in our study cohort were comparable to those within the fast-forward trial. In terms of post-RT skin toxicity, fewer patients reported any toxicity in the UHB patient cohort versus those in the trial, and the number of Grade 2/3 toxicities reported was also low. A delay in toxicity reporting from 2 weeks for 40Gy/15 to 3 weeks for 26Gy/5 was observed.
Conclusion:
Our study concluded that offering ultrahypofractionation was convenient for patients; reducing the number of hospital visits during the SARS-CoV-2 virus pandemic appeared safe in terms of acute post-RT-related skin toxicity. The reduced hospital visits limited exposure of patients and staff to the SARS-CoV-2 virus while also ensuring efficient use of Radiotherapy Department resources. Local follow-up protocols have been amended to ensure review at 3 weeks for the 26Gy/5 schedule to acknowledge the delay in acute toxicity development. To date, there is only 5-year toxicity and relapse data available from the fast-forward trial; therefore, hypofractionation schedules should be offered to patients as long as they fulfil the criteria and understand the limitations of the study as well as accelerated peer review processes in the face of the pandemic.
To evaluate the use of exercise in managing fatigue in breast cancer patients undergoing adjuvant radiotherapy. To explore the effectiveness of different exercise practices and explore how optimum management of fatigue might be achieved.
Method
A CINAHL (Cumulative Index to Nursing and Allied Health Literature) database search of literature was undertaken and publications screened for retrieval with 24 qualifying for inclusion in the review.
Results
There is evidence to support various forms of exercise including aerobic, resistance, alternative and combination exercise in the management of fatigue in early stage breast cancer patients undergoing adjuvant radiotherapy. The benefits of exercise for patients with later stage and metastatic disease is less clear and there is a lack of published research related to this category of patient.
Conclusion
Exercise is considered a safe, non-pharmacological intervention for early stage breast cancer patients receiving adjuvant radiotherapy. Further investigation is required into optimum exercise interventions and the effectiveness and viability of supervised and unsupervised models. Patient centred tailored advice and guidance needs to be developed and effectively promoted by therapeutic radiographers in order for patients to fully realise the benefit.
Sinonasal malignant melanoma is a relatively rare malignancy with poor prognosis, and effective treatments remain elusive. This analysis aimed to explore whether post-operative radiotherapy conferred any survival advantages in patients with this disease when compared with surgery alone.
Methods
Published studies were identified by searching four electronic databases. The endpoints evaluated were: rates of overall survival, disease-free survival and local control.
Results
Twenty-eight studies including 1392 patients were identified. The results indicated that post-operative radiotherapy led to a significantly better three-year overall survival rate (p = 0.02), and suggested a borderline significant benefit for five-year overall survival (p = 0.05), when compared with surgery alone. However, no statistical advantage was found for disease-free survival, local control or one-year overall survival.
Conclusion
This meta-analysis indicated that adjuvant radiotherapy prolonged survival, but showed no benefit for disease-free survival or local control.
There is no consensus on how long the initiation of radiotherapy (RT) can be delayed after surgery without a negative impact on survival.
Materials and methods
We conducted a retrospective study of 278 patients with stage 0–II breast cancer, all of whom were treated with surgery and RT, with those at stages I–II also receiving chemotherapy. Patients were followed-up for 5 years after diagnosis to assess disease-free and overall survival.The independent variable was the delay in the initiation of RT, assessed by two criteria: time since the last treatment, considered acceptable if ≤6 weeks, and time since surgery, considered acceptable if ≤7 months, these cut-offs being used to categorise patients into two groups according to the length of delay.
Results
No statistically significant differences were observed in the probability of disease-free survival (p=0·412) or overall survival (p=0·890). The appearance of recurrence was 5–59 months, with an average of 38·50 (14·31).
Conclusions
Delaying the initiation of RT for more than 6 weeks after last treatment does not seem to have a negative impact on disease-free or overall survival.
A multidisciplinary team approach is required for the preservation of voice and appropriate management of glottic cancer. This study aimed to investigate the outcomes of surgically treated glottic cancers of all stages. All aspects of surgical management, such as laser cordectomy, partial laryngectomy, total laryngectomy with voice prosthesis, and salvage laryngectomy, conducted at a single tertiary care institute in India, were reviewed.
Method:
A retrospective analysis of hospital records was performed for 192 glottic cancer patients who were surgically treated between 2003 and 2007.
Results:
Patients with tumour stages 1 or 2 glottic cancer treated with laser cordectomy had a local control rate of 85 per cent and five-year survival rate of 98.6 per cent. The findings suggest that the number of partial laryngectomies performed for stage 3 tumours is declining. Patients with a tumour stage 3 lesion with a fixed hemilarynx or a tumour stage 4 lesion, treated with total laryngectomy, were found to have a five-year survival rate of 61.6 per cent. Nodal status was significantly associated with five-year survival rate.
Conclusion:
Surgery offers a viable five-year survival rate in glottic cancer patients.
The rarity of vulval cancer has meant that few, if any, robust randomised trials have been performed. Women with predisposing conditions should be counselled with regard to risk. This rarity, combined with the modesty that women might feel owing to the intimate location of the problem means that cancer might be easily overlooked, misdiagnosed or ignored. Diagnosis of vulval cancer is made based on biopsy. The major factors that influence treatment planning are the need to assess nodal status, the extent of the disease and the woman's suitability for treatment. Pelvic node involvement tends to follow inguinofemoral spread of disease. Preoperative radiotherapy should be considered if primary surgery is likely to compromise sphincter function. The requirement for reconstruction should be considered in all patients undergoing surgery for vulval cancer. Sentinel node sampling is a recent innovation, which provides diagnostic information to direct further care while minimising morbidity.
