Adherence Outcomes and Risk Factors Predicting Nonadherence to Active Surveillance in Patients With Stage 1 Testicular Germ Cell Tumors.

Adherence to active surveillance in patients with stage 1 testicular cancers may be influenced by factors affecting capacity and motivation to attend appointments. The aims of this study were to assess adherence to active surveillance and analyze factors which may impact adherence.

A retrospective cohort study was conducted in patients diagnosed with stage 1 testicular cancer between 2005 and 2020, and managed with active surveillance at 3 institutions in South Western Sydney, Australia. Adherence with active surveillance was followed to 2023 and patients were subsequently classified into 3 groups: "Optimal," "Adequate" or "Loss to follow-up" (LTFU). Factors for adherence were analyzed using multivariable logistic regression. Disease recurrence was analyzed using multivariable Cox regression.

In 125 patients, adherence with active surveillance was assessed as "Optimal" in 64 (51%), "Adequate" in 14 (11%), and LTFU in 47 (38%). Multivariable analysis demonstrated that patients had higher odds of being in the "Optimal" or "Adequate" categories if they were from a culturally and linguistically diverse background (OR 4.86, P = .026), nonsmokers (OR 7.63, P = .0002), not employed (OR 4.93, P = .0085), had a partner (OR 2.74, P = .0326), or were diagnosed after June 2016 (OR 5.22, P = .0016). Recurrence occurred in 21 patients (17%). The risk of recurrence increased with the presence of multiple pathological risk factors (HR 5.77, P = .0032), if patients were unemployed (HR 2.57, P = .032), or if they had "Optimal" or "Adequate" adherence (HR 12.74, P = .0136).

Adherence with active surveillance was poorer in this cohort of stage 1 testicular cancer patients. Patients from culturally and linguistically diverse backgrounds and those who were nonsmokers, unemployed, with a partner, and later date of diagnosis, were more likely to be adherent with active surveillance.
