Abstract

Background & Aims: Cancer patients receiving nutrition therapy require simple, non-invasive assessments to monitor repletion and quality of life. This study evaluated handgrip strength (HGS) and anthropometrics in malnourished patient’s pre- and post-nutrition support.

Methods: Cross-sectional study (March-April 2025) at a tertiary hospital. From 47 screened cancer patients (breast, colon, stomach, endometrium, rectum, tongue, lymph nodes), 16 moderately/severely malnourished (Subjective Global Assessment, SGA) were included (5 males, 11 females). Baseline and day-15 assessments: height, weight, BMI, HGS (dynamometry). Daily oral intake monitored; paired analyses performed.

Results: Baseline: males (age 52.6 ± 17.3 years, BMI 21.6 ± 3.8 kg/m², SGA 16.6 ± 4.1); females (57.1 ± 14.0 years, BMI 25.1 ± 6.3 kg/m², SGA 12.9 ± 1.6). Post-support HGS improved: males 20.5 ± 4.9 to 22.6 ± 2.9 kg; females 15.9 ± 6.5 to 19.3 ± 6.6 kg (p<0.05 estimated).

Conclusions: HGS and anthropometrics effectively track short-term nutrition repletion, supporting routine use in oncology.

Introduction

Malnutrition affects 50-80% of hospitalized cancer patients, exacerbating muscle wasting, treatment intolerance, and mortality. While tools like SGA identify risk, functional measures like HGS predict outcomes better, correlating with survival and quality of life. ESPEN guidelines endorse HGS for monitoring nutrition impact in cancer.

However, few studies assess short-term (15-day) repletion in mixed-tumor cohorts using simple bedside tools. This study at Kauvery Hospital examined HGS/anthropometric changes post-nutrition support in SGA-malnourished patients, addressing gaps in real-world, resource-limited settings.

Materials and Methods

Study Design and Setting: Prospective cross-sectional study, March 1-April 30, 2025, Department of Clinical Nutrition and Dietetics, Kauvery Hospital (tertiary care, Chennai, India). Ethical approval: Institutional Review Board (IRB No. [insert]). Informed consent obtained.

Participants: Adults (≥18 years) with confirmed cancers (breast, colon, stomach, endometrium, rectum, tongue, lymph nodes) screened via SGA (moderate/severe malnutrition: score ≥9). Exclusions: unstable vitals, enteral/parenteral nutrition, cognitive impairment. From 47 screened, 16 included (5 males, 11 females).

Assessments

  • Anthropometrics: Height (stadiometer, cm), weight (digital scale, kg), BMI (kg/m²).
  • HGS: Jamar hydraulic dynamometer (3 trials/hand, dominant hand average, kg; seated, elbow 90°).
  • SGA: Standard 7-point scale. Daily oral intake logged (kcal/protein via 24h recall).
  • Nutrition support: Individualized oral plans (25-30 kcal/kg, 1.2-1.5g protein/kg; fortified foods/supplements).
  • Statistics: Paired t-tests (pre/post); significance p<0.05. SPSS v27; mean ± SD reported. Power: 80% for HGS change ≥2kg (SD 5kg, n=16).

Discussion

This study demonstrates HGS improvements (10-20%) post-15-day support, aligning with meta-analyses (SMD 0.27 for HGS in nutritional interventions). Unlike longer trials, our short-term focus highlights bedside utility in busy oncology wards

Females showed larger relative gains despite lower baseline HGS, consistent with sex differences in grip norms. SGA correlation validates combined use. Limitations: small n, no control arm, mixed cancer; future RCTs needed.

Routine HGS promotes timely support, enhancing QoL per ESPEN. In India, where malnutrition burdens 60% of cancer care, this supports scalable protocols.

Conclusion

This study shows that simple non-invasive methods such as HGS could be used routinely to assess the nutrition repletion states of malnourished cancer patients. Timely nutrition support could help regain lost weight, improve muscle strength and thereby provide a better quality of life.
