Edema of Advanced Cancer: Prevalence, Etiology, and Conservative Management-A Single Hospice Cross-Sectional Study

Dermatological Issues Among Individuals Receiving Palliative Care - A Review

Skin disorders among individuals receiving palliative care may be associated with the primary condition or underlying comorbidities and patients may experience pruritus, discomfort or pain. Common conditions include xerosis, pressure ulcers, intertrigo, superficial fungal infections, telogen effluvium, pruritus, herpes zoster, eczematous disorders and edema. During end-of-life care, there is reduced skin perfusion and metabolism hence leading to susceptibility to infection, pressure and injury. Other factors affecting the skin include limited mobility, nutritional deficits and immunosuppression. Although treatment strategies for each skin condition are usually aligned with standard protocols, considerations among these patients include limited life-expectancies, potential treatment burden, drug-drug interactions as well as comfort-directed rather than cure-directed therapy. For patients with xerosis cutis, the regular use of moisturisers is recommended. The management and prevention of pressure ulcers include the strategies of skin assessment and care, pressure redistribution, nutrition and hydration and ulcer care. Superficial fungal infections require treatment with appropriate topical and/or systemic antifungals while antivirals and adjunctive treatment can be prescribed for herpes zoster. Treatment and symptom control of skin disorders in this population can improve quality of life and patients' comfort level.

Identifying cancer patients who received palliative care using the SPICT-LIS in medical records: a rule-based algorithm and text-mining technique

BACKGROUND

Due to limited numbers of palliative care specialists and/or resources, accessing palliative care remains limited in many low and middle-income countries. Data science methods, such as rule-based algorithms and text mining, have potential to improve palliative care by facilitating analysis of electronic healthcare records. This study aimed to develop and evaluate a rule-based algorithm for identifying cancer patients who may benefit from palliative care based on the Thai version of the Supportive and Palliative Care Indicators for a Low-Income Setting (SPICT-LIS) criteria.

METHODS

The medical records of 14,363 cancer patients aged 18 years and older, diagnosed between 2016 and 2020 at Songklanagarind Hospital, were analyzed. Two rule-based algorithms, strict and relaxed, were designed to identify key SPICT-LIS indicators in the electronic medical records using tokenization and sentiment analysis. The inter-rater reliability between these two algorithms and palliative care physicians was assessed using percentage agreement and Cohen's kappa coefficient. Additionally, factors associated with patients might be given palliative care as they will benefit from it were examined.

RESULTS

The strict rule-based algorithm demonstrated a high degree of accuracy, with 95% agreement and Cohen's kappa coefficient of 0.83. In contrast, the relaxed rule-based algorithm demonstrated a lower agreement (71% agreement and Cohen's kappa of 0.16). Advanced-stage cancer with symptoms such as pain, dyspnea, edema, delirium, xerostomia, and anorexia were identified as significant predictors of potentially benefiting from palliative care.

CONCLUSION

The integration of rule-based algorithms with electronic medical records offers a promising method for enhancing the timely and accurate identification of patients with cancer might benefit from palliative care.

Preventing lower limb lymphedema after pelvic lymphadenectomy with progressive resistance exercise training: A randomized controlled trial

Objective

This study aimed to assess the efficacy of a self-designed progressive resistance exercise training program for preventing the development of lower limb lymphedema.

Methods

An open-label randomized controlled trial was conducted in patients who underwent radical surgery for cervical cancer treatment in our department between October 7, 2019, and October 7, 2021. The participants were randomly assigned to one of three groups: progressive resistance exercise training, graduated compression stocking, and control group.

Results

A total of 267 patients were enrolled (89 in each group). The incidence of lower limb lymphedema was 9.0% (n = 8) in the progressive resistance exercise training group, 28.1% (n = 25) in the graduated compression stocking group, and 42.7% (n = 38) in the control group. Over the 2-year follow-up period, the risk of lower limb lymphedema was significantly lower in the progressive resistance exercise training group than in the control group, with a hazard ratio (HR) (95% confidence interval [CI]) of 0.156 (0.073-0.335). The study was underpowered to demonstrate a statistically significant reduction in risk in the graduated compression stocking group, with an HR (95% CI) of 0.624 (0.376-1.033).

Conclusions

Progressive resistance exercise training is an effective strategy for preventing lower limb lymphedema after pelvic lymphadenectomy for cervical cancer. It imposes no additional economic burden and can be performed conveniently without the need for dedicated exercise facilities. This makes it particularly accessible to patients in developing countries, allowing them to exercise at their convenience.

Management of Peripheral Edema in Patients with MET Exon 14-Mutated Non-small Cell Lung Cancer Treated with Small Molecule MET Inhibitors

Small molecule mesenchymal-epithelial transition (MET) inhibitors, such as crizotinib, capmatinib, and tepotinib, are treatment options for metastatic non-small cell lung cancer (NSCLC) in adult patients whose tumors have a mutation that leads to MET exon 14 skipping. In clinical trials, these MET inhibitors were associated with a high incidence of peripheral edema, although this was generally mild-to-moderate in severity. There is limited information about the mechanism involved in MET inhibitor-induced peripheral edema. Perturbation of hepatocyte growth factor (HGF)/MET signaling may disrupt the permeability balance in the vascular endothelium and thus promote edema development. Another potential mechanism is through effects on renal function, although this is unlikely to be the primary mechanism. Because edema is common in cancer patients and may not necessarily be caused by the cancer treatment, or other conditions that have similar symptoms to peripheral edema, a thorough assessment is required to ascertain the underlying cause. Before starting MET-inhibitor therapy, patients should be educated about the possibility of developing peripheral edema. Patient limb volume should be measured before initiating treatment, to aid assessment if symptoms develop. Since the exact mechanism of MET inhibitor-induced edema is unknown, management is empiric, with common approaches including compression stockings, specific exercises, massage, limb elevation, and/or diuretic treatment. Although not usually required, discontinuation of MET inhibitor treatment generally resolves peripheral edema. Early diagnosis and management, as well as patient information and education, are vital to decrease the clinical burden associated with edema, and to reinforce capmatinib treatment adherence.

Relationship between Phase Angle and Objective and Subjective Indicators of Nutritional Status in Cancer Patients: A Systematic Review

To investigate the relationship between phase angle (PA) and objective and subjective indicators of nutritional status in cancer patients, as well as to identify cutoff points for PA, to detect malnutrition in these patients. The study was a systematic review, carried out following the guidelines of the Preferred Reporting Items for Systematic Reviews and meta-analyses (PRISMA). Literature search was performed for two authors, in indexed databases, including the National Library of Medicine, Bethesda, MD (PubMed), Latin American and Caribbean Literature in Health Sciences (LILACS), and Scopus (Elsevier). We used the checklist from the Joanna Briggs Institute for assessing the risk of bias. The review was registered with the Systematic Review Registration (PROSPERO), number CRD42020134324. In total, nine papers were eligible. PA was correlated with several objective and subjective indicators of nutritional status in most cases. Cutoff point values for the PA, capable of detecting malnutrition, varied from 4.73° to 6°, despite the modest diagnostic accuracy. We assume that PA may be considered an indicator of nutritional status, when complementing additional data and assisting health practitioners in evaluating individuals with malignant neoplasms. However, a single cutoff point with fair and concomitant sensitivity and specificity was not identified.

Multicomponent Compression Bandaging Combined with Diuretic Therapy of Anasarca Secondary to Palliative Chemotherapy: A Case Report

Background: Although decongestive physiotherapy combined with diuretics may be efficient in limb edemas, no such therapy has been described in the context of anasarca. Case Description: A bedbound 62-year-old man with stage IV pancreatic cancer, presenting with progressing severe dyspnea at rest and anasarca, was admitted to the free-standing hospice 3 weeks after receiving nab-paclitaxel with gemcitabine. Two weeks before admission, oral loop and potassium-sparing diuretics were started for bilateral lower limb edema, which progressed to anasarca even though the drug dose was increased. Hypotension hindered further dose escalation of diuretics. Supportive multicomponent bandage compression on both legs with concurrent intravenous furosemide in hypersaline infusion was implemented with good clinical toleration. Afterward, the loop diuretic dose was increased, and supplemented with dexamethasone. A spectacular edema decrease and marked dyspnea improvement with 19 kg body weight reduction were observed within 7 days. Furosemide was switched to oral route and the patient was discharged needing only occasional assistance in daily living. Conclusion: Compression bandaging with diuretic therapy may be considered even in advanced generalized edemas; however, further studies are needed to determine the adequate therapeutic regime.

Lay Caregivers Education in Multicomponent Compression Bandaging in Obese Patients with Lower Limb Edema: A Case-Control Pilot Study

Background: A report on the usefulness of the instruction of lay carers in multilayer short-stretch compression bandaging within the initial intensive phase physical treatment of mixed-etiology chronic lower limb edema. Methods and Results: In a group of adult obese patients (including 24 females) with venous insufficiency and chronic bilateral lower limb edema, and without a history of physical therapy, 20 (ambulatory managed) were bandaged once daily (four layers, short stretch with cotton tube, and foam padding underneath) for 3 weeks (Monday-Friday) by skilled physiotherapists, and in 20 cases (education group, EG), the patients' lay carers were educated by these physiotherapists according to the same regime during one session. The outcome measures included limb volume (the method of circumference measurement with a tape at 4 cm intervals) after 1, 3, and 6 months, the time to reach the maintenance phase, the frequency of complementary bandaging during this phase, and the sense of self-efficacy (General Self-Efficacy scale, GSEs). No significant differences were noted between the two groups in the baseline measurements of age, body mass, and limb volume. The carers were able to apply compression bandages in all cases during the observation period. The time to reach the maintenance phase was longer in EG (6 vs. 1 weeks; p < 0.001). A similar median reduction in edema volume was observed at the end of the bandaging period, which continued for 3 and 6 months. It was only in EG that further improvement between 1 and 3 months was observed (p = 0.008). All participants represented an equally high optimistic sense of personal competence (GSEs). Conclusions: The instruction of lay carers in bandaging may provide a simple clinically effective solution for lower limb edema management, thus lowering its costs.
