In the appendiceal cohort (mean age 51.5 years; median PCI 30), all 12 underwent bilateral diaphragm intervention (four with full-thickness resection) with CCR 0\u20131. Time to chest recurrence ranged from 0.3 to 82.8\u00a0months; half experienced early respiratory complications (e.g., pleural effusion, pneumothorax). In the mesothelioma cohort (mean age 44.9 years; median PCI 22.1), seven had bilateral stripping (two with resection) and one had unilateral stripping; CCR was 0\u20131. Recurrence occurred between 8.0 and 85.4\u00a0months (median \u223c31.4\u00a0months); half had early respiratory compromise. No significant associations were observed between PCI, CCR, or extent of diaphragmatic intervention and recurrence risk, although ICU stay and CCR weakly correlated with recurrence in mesothelioma.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec id=\"j_pp-2025-0010_abs_004\">\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Pleuropulmonary recurrence following CRS\/HIPEC with diaphragm intervention is rare (2.7\u202f%), with early recurrences suggesting occult thoracic involvement.
