RESUMO
PURPOSE: Patients with Germ cell tumours (GCT) are at risk of long-term toxicities due to multimodality therapy. It is debatable whether there is an impact on the quality of life(QoL) of GCT survivors. METHODS: A case-control study was conducted at a tertiary care centre in India, using the EORTC QLQ C30 questionnaire, to compare the QoL between GCT survivors(disease free > 2 years) and healthy matched controls. A multivariate regression model was used to identify factors affecting QoL. RESULTS: A total of 55 cases and 100 controls were recruited. Cases had a median age of 32 years (interquartile range, IQR 28-40 years), ECOG PS of 0-1(75%), advanced stage III (58%), chemotherapy (94%) and 66% were > 5 years from diagnosis. The median age of controls: 35 years (IQR 28-43 years). A statistically significant difference was seen for emotional (85.8 ± 14.2 vs 91.7 ± 10.4, p 0.005), social(83.0 ± 22.0 vs 95.2 ± 9.6, p < 0.001) and global scales (80.4 ± 21.1 vs 91.3 ± 9.7, p < 0.001). Cases had more nausea and vomiting(3.3 ± 7.4 vs 1.0 ± 3.9, p 0.015), pain(13.9 ± 13.9 vs 4.8 ± 9.8, p < 0.001), dyspnea(7.9 + 14.3 vs 2.7 ± 9.1, p 0.007), and appetite loss(6.7 ± 14.9 vs 1.9 ± 7.9, p 0.016) and greater financial toxicity(31.5 ± 32.3 vs 9.0 ± 16.3, p < 0.001). Adjusting for age, performance status, BMI, stage, chemotherapy, RPLND, recurrent disease, and time since diagnosis, no predictive variables were significant. CONCLUSION: There is a detrimental impact of history of GCT in long term survivors of GCT.
RESUMO
Objectives: To qualitatively assess the clinical usefulness of patient-specific high-fidelity three-dimensional (3D) print model of kidney before partial nephrectomy (PN) and to identify subset domains where it may help in clinical terms. Materials and Methods: Thirteen 3D models were printed for tumors having RENAL nephrometry score of ≥8. Their usage for PN was assessed prospectively using a qualitative questionnaire to be answered on a Likert scale of 1-10. The questions focused on realistic resemblance, preoperative dry surgical run, intertest comparison, surgical impact, and overall beneficence domains as perceived by primary surgeons with respect to surgical conduct during PN. Results: Mean RENAL score was 9.15 (8-11). Models were rated high (9.07 ± 0.86) for realistic resemblance domain and were rated better than contrast-enhanced computed tomography (CECT) (8.38 ± 0.87) and intraoperative ultrasonography (8.07 ± 1.26) for orientation regarding resection margins. A further marginal improvement to 8.2 ± 0.84 was noted against ultrasound where surgeon did a dry cut preoperatively. Use of superselective arterial approach in four, precise awareness about dissection of a major vessel in four, retroperitoneoscopic approach in one, and surgical margin awareness in three were directly attributed to the model. Overall utility of having a model printed was rated high (8.23 ± 1.3). Conclusion: The 3D print models of complex renal tumors have high realistic resemblance to actual patient's anatomy. They were rated better than preoperative CECT or intraoperative ultrasonography for orientation regarding surgical resection margins. It may also help change or modify the surgical plan in a subset of patients with a potential to improve overall outcomes in these complex cases.
