Hypofractionated radiation therapy for durable palliative treatment of bleeding, fungating breast cancers

Caring for Patients With Malignant Fungating Wounds: A Scoping Literature Review

PURPOSE

The aim of this scoping literature review was to identify current knowledge related to management of malignant fungating wounds (MFWs), gaps in this knowledge, and areas for future research.

METHODS

This was a scoping literature review.

SEARCH STRATEGY

Six electronic databases (Embase, MEDLINE, Cochrane (CENTRAL), CINAHL, Scopus, and Web of Science) were searched spanning the years 1987 and 2022. The initial electronic database search retrieved 6041 studies. The search is based on 60 articles published between 1987 and 2022, along with 14 additional studies were based on search of reference lists of key articles.

FINDINGS

Studies were divided into 2 main domains; the vast majority (65 of 72, 87.8%) focused on symptom impact, measurement, and management. The remaining articles (n = 9, 12.2%) focused on caring for patients with MFW; these studies focused on nursing care experiences and competencies, along with lay caregiver experiences. Findings indicated that instruments have been developed to evaluate symptoms of MFW but only a few have been validated. Most of the studies reviewed evaluated the influence of MFW on physical and psychosocial function. Local and systematic symptom managements such as modern dressings, wound care strategies, surgery, and radiotherapy as well as chemotherapy were found to be effective in alleviating symptoms. Findings also indicated that families and nurses encounter obstacles and burdens when caring for patients with MFW; limited studies were retrieved that investigated the competence and needs of nurses in their caring journey.

IMPLICATIONS

Future studies should focus on: (1) using better designs to evaluate and compare topical agents and dressings to control odor, (2) validating assessment tools specific to MFW, (3) qualitative studies designed to enhance understanding family and nurses' experiences, and (4) improving the nurse's ability to care for patients with MFWs and their responses to managing these challenging patients.

Fungating and Ulcerating Breast Cancer: Wound Closure Algorithm, Complications, and Survival Trends

Fungating breast cancer severely affects patients' daily lives, and patient management poses major oncology challenges. To present 10-year outcomes of unique tumor presentation, suggesting a focused algorithm for surgical management and providing deep analysis for factors affecting survival and surgical outcomes. Eighty-two patients with fungating breast cancer were enrolled in the period from January 2010 to February 2020 in the Mansoura University Oncology Center database. Epidemiological and pathological characteristics, risk factors, different surgical treatment techniques, and surgical and oncological outcomes were reviewed. Preoperative systemic therapy was used in 41 patients, with the majority (77.8%) showing progressive response. Mastectomy was performed in 81 (98.8%) patients, with primary wound closure in 71 (86.6%), and wide local excision in a single patient (1.2%). Different reconstructive techniques in non-primary closure operations were used. Complications were reported in 33 (40.7%) patients, of which 16 (48.5%) were of Clavien-Dindo grade II category. Loco-regional recurrence occurred in 20.7% of patients. The mortality rate during follow-up was 31.7% (n = 26). Estimated mean overall survival (with 95% CI) was 55.96 (41.98-69.9) months; estimated mean loco-regional recurrence-free survival (with 95% CI) was 38.01 (24.6-51.4) months. Surgery is a cornerstone fungating breast cancer treatment option, but at the expense of high morbidity. Sophisticated reconstructive procedures may be indicated for wound closure. A suggested algorithm based on the center's experience of wound management in difficult mastectomy cases is displayed.

Short Stay Management of Locally Advanced Breast Cancer Using Immediate Local Thoracoabdominal Advancement Flap and Enhanced Recovery After Surgery Protocol

BACKGROUND

Patients with locally advanced invasive breast cancer (LABC) are often considered inoperable, because of the anticipated chest wall defect and need for complex reconstruction. We present a series of patients who underwent mastectomy with extensive skin resection and immediate chest wall reconstruction using a local thoracoabdominal advancement flap (TAAF). All patients were managed after surgery with an ERAS (Enhanced Recovery After Surgery) protocol, to decrease length of stay in hospital. We also present 1 patient who subsequently had satisfactory bilateral delayed breast reconstruction with pedicled latissimus dorsi myocutaneous flaps with prepectoral silicone implants.

METHODS

This is a single-surgeon, single-institution retrospective chart review of patients with LABC who underwent mastectomy with skin resection and local TAAF from May 2017 to October 2019, with minimum 3-month follow-up.

RESULTS

Thirteen patients met inclusion criteria. Twelve of 13 patients presented with stage III or IV invasive breast cancer, with skin involvement. The mean chest wall defect measured 248.7 cm2 (140-336 cm2; SD, 63.2 cm2), and all were successfully reconstructed with immediate local TAAF. There were no intraoperative complications, but 1 patient developed a postop hematoma. The mean hospital stay was 1.3 nights, with 9 patients (69.2%) staying less than 23 hours and 4 patients (30.8%) staying 2 nights. Nine patients (69.2%) underwent adjuvant therapy, beginning on average 32 days (13-55 days; SD, 13.1 days) after surgery. The mean follow-up time was 13.8 months (4.5-31.6 months; SD, 9.2 months). One patient underwent successful delayed bilateral breast reconstruction with pedicled latissimus dorsi myocutaneous flaps and silicone implant placement.

CONCLUSIONS

Our study demonstrates that reconstruction with local TAAF is an outpatient procedure that reliably provides durable, immediate chest wall coverage, after mastectomy in patients with LABC. This technique has a short operative time, low blood loss, and low complication rate, allowing timely adjuvant therapy. Using an ERAS postop protocol we were able to reduce mean hospital stay to 1.3 days. Compared with other described techniques of reconstruction, the additional scars and donor site morbidity are minimal, allowing for delayed breast reconstruction. We also present survival outcomes data on these surgically managed patients.

Relationship Between Neutrophil-To-Lymphocyte Ratio and Brain Metastasis in Non-Small Cell Lung Cancer Patients

Objective

To investigate the relationship between the neutrophil-to-lymphocyte ratio (NLR) of patients with non-small cell lung cancer (NSCLC) and their risk of developing brain metastases after adjusting for confounding factors.

Methods

A retrospective observational study of the general data of patients with NSCLC diagnosed from January 2016 to December 2020. Multivariate logistic regression was used to calculate the dominance ratio (OR) with 95% confidence interval (CI) for NLR and NSCLC brain metastases with subgroup analysis. Generalized summation models and smoothed curve fitting were used to identify whether there was a nonlinear relationship between them.

Results

In all 3 models, NLR levels were positively correlated with NSCLC brain metastasis (model 1: OR: 1.12, 95% CI: 1.01-1.23, P = .025; model 2: OR: 1.16, 95% CI: 1.04-1.29, P = .007; model 3: OR: 1.20, 95% CI: 1.05-1.37, P = .006). Stratified analysis showed that this positive correlation was present in patients with adenocarcinoma (LUAD) and female patients (LUAD: OR: 1.30, 95% CI: 1.10-1.54, P = .002; female: OR: 1.52, 95% CI: 1.05-2.20, P = .026), while there was no significant correlation in patients with squamous carcinoma (LUSC) and male patients (LUSC: OR:0.76,95% CI:0.38- 1.53, P = .443; male: OR:1.13, 95% CI:0.95-1.33, P = .159).

Conclusion

This study showed that elevated levels of NLR were independently associated with an increased risk of developing brain metastases in patients with NSCLC, and that this correlation varied by TYPE and SEX, with a significant correlation in female patients and patients with LUAD.

Radiation Therapy for Advanced Mucinous Carcinoma of the Breast With a Malignant Wound: A Case Report

Patients with breast cancer who refuse standard treatment often suffer from malignant wounds due to the growth of local tumors. However, treatment strategies for patients with unresectable locally advanced breast cancer who refuse standard treatment remain unclear. Usually, such cases are treated with palliative irradiation and do not achieve local control by irradiation alone. This is the first case report discussing the role of high-dose local irradiation and the treatment course for a patient with a massive breast tumor (mucinous adenocarcinoma) who refused standard treatment. A 44-year-old female was diagnosed with mucinous carcinoma of the breast in the right breast (cT1N0M0, cStage I). She refused standard treatment for six years. She visited the emergency department because of acute bleeding from the right breast with malignant wounds. Macroscopically, the tumor in the right breast measured over 20 cm in diameter. The tumor was exudative, exhibited ulceration and slight bleeding, and emitted an odor. Imaging findings showed multiple lymph nodes and bone metastases, and the final diagnosis was stage IV breast cancer (cT4bN1M1). Although the surgeon recommended chemotherapy for breast cancer, the patient refused chemotherapy or other therapy due to concerns regarding treatment-related complications. Considering the symptoms of advanced breast cancer with malignant wounds, she finally agreed to receive radiation therapy (RT). We performed RT at 70 Gy in 35 fractions over seven weeks. The tumor-associated symptoms disappeared after RT. Three months after RT, the tumor had almost disappeared. We administered luteinizing hormone-releasing hormone agonists after RT. Two years after RT, she died due to multiple liver metastases and ascites; however, there was no disease progression in the right breast. High-dose RT for locally advanced mucinous carcinoma of the breast with malignant wounds is considered an effective therapeutic option.

Palliative Radiotherapy for Advanced Cancers: Indications and Outcomes

Palliative radiotherapy (PRT) is well-tolerated, effective treatment for pain, bleeding, obstruction, and other symptoms/complications of advanced cancer. It is an important component of multidisciplinary management. It should be considered even for patients with poor prognosis, because it can offer rapid symptomatic relief. Furthermore, expanding indications for treatment of noncurable disease have shown that PRT can extend survival for select patients. For those with good prognosis, advanced PRT techniques may improve the therapeutic ratio, maximizing tumor control while limiting toxicity. PRT referral should be considered for any patient with symptomatic or asymptomatic sites of disease where local control is desired.
