The Geriatric G8 Score Is Associated with Survival Outcomes in Older Patients with Advanced Prostate Cancer in the ADHERE Prospective Study of the Meet-URO Network

Prognostic factors for overall survival in clinical node-positive patients with upper tract urothelial carcinoma

BACKGROUND

There is sparse evidence regarding optimal management and prognosticators for oncologic outcomes in patients with clinical node-positive (cN+) upper tract urothelial carcinoma (UTUC).

METHODS

We retrospectively analyzed the data from 105 UTUC patients with cN1-2M0 between June 2010 and June 2022 at multiple institutions affiliated with our university. At the time of diagnosis, all patients received standard-of-care treatment including radical nephroureterectomy (RNU), chemotherapy, and/or palliative care. We employed a Cox regression model to analyze the prognostic importance of various factors on overall survival (OS).

RESULTS

Of 105 patients, 54 (51%) underwent RNU, while 51 (49%) did not. RNU was likely to be selected in patients with younger and higher G8 score, resulting in better median OS in patients who underwent RNU than in those who did not (42 months vs. 15 months, p < 0.001). Multivariable analysis among the entire cohort revealed that low G8 score (≤14) (hazard ratio [HR]: 2.07, 95% confidence interval [CI]: 1.08-3.99), elevated pretreatment C-reactive protein (CRP) (HR: 3.35, 95%CI: 1.63-6.90), and failure to perform RNU (HR: 2.16, 95%CI: 1.06-4.42) were independent prognostic factors for worse OS. In the subgroup analyses of cohorts who did not undergo RNU, elevated pretreatment CRP was the only independent prognostic factor for worse OS in cN+ UTUC patients.

CONCLUSIONS

RNU seems to be a reasonable treatment option in cN+ UTUC patients where applicable. Elevated pretreatment CRP appears to be a reliable prognosticator of worse OS and may be helpful in optimizing candidate selection for intensified treatment in this setting.

Instrumental activities of daily living in older patients with metastatic prostate cancer: results from the meet-URO network ADHERE prospective study

Instrumental activities of daily living (IADL) are significant health indicators closely related to executive functions and able to detect mild cognitive impairment. A decline in IADL usually precedes ADL limitation, including taking medications, and may therefore predict a cognitive decline. We aimed to investigate the association of patients' IADL score with other clinical factors, with a particular focus on the presence of a caregiver, and the impact on adherence to androgen receptor pathway inhibitors (ARPIs) and survival outcomes within the Meet-URO 5-ADHERE study. It was a large prospective multicentre observational cohort study monitoring adherence to ARPIs in 234 metastatic castrate-resistant PC (mCRPC) patients aged ≥ 70. We observed an association between impaired IADL and lower geriatric G8 scores (p < 0.01), and lower adherence to ARPIs whether assessed by pill counting (p = 0.01) or self-reported by the patient himself (p = 0.03). The combination of an IADL < 6 and the absence of a caregiver resulted in a significantly high risk of non-adherence to the ARPIs at the multivariable analysis (HR 9.23, 95% confidence interval 2.28-37.43, p = 0.01). IADL alongside the geriatric G8 scales represent essential tools to identify frail and less auto-sufficient patients who are extremely vulnerable particularly if not supported by a caregiver and have the highest risk of nonadherence to ARPIs.

Assessing the role of colonic and other anatomical sites uptake by [18 F]FDG-PET/CT and immune-inflammatory peripheral blood indexes in patients with advanced non-small cell lung cancer treated with first-line immune checkpoint inhibitors

BACKGROUND

Inflammation in non-small cell lung cancer (NSCLC) may impair the response to immune checkpoint inhibitors (ICIs) and can be indicated by peripheral blood inflammatory indexes. 2-deoxy-2-[18 F]fluoro-D-glucose positron emission tomography/computed tomography ([18 F] FDG-PET/CT) may be used as a marker of inflammation by measuring glucose metabolism in different colonic sites.

METHODS

This retrospective analysis aimed to investigate the correlation between [18 F] FDGPET/CT SUVratio in six gastrointestinal districts, the spleen, the pharynx and the larynx alongside the most avid tumor lesion with peripheral blood inflammatory indexes, including the neutrophil-to-lymphocyte ratio (NLR), systemic immune-inflammatory index (SII, i.e., NLR times platelets) and lactate dehydrogenase (LDH), in patients with [18 F] FDG-PET/CT staged IV NSCLC who received first-line immune checkpoint inhibitors (ICIs). The role of SUVratios and peripheral blood inflammatory indexes in predicting overall survival (OS) and progression-free survival (PFS) was then explored.

RESULTS

A total of 43 patients were treated with first-line ICI alone (58%) or in combination with chemotherapy (42%). A significant correlation was only found between the rectosigmoid SUVratio and NLR (p = 0.0465). NLR >5.5 and LDH > 333.5 were associated with a worse OS (p = 0.033 and p = 0.009, respectively). The SII was associated with a worse PFS in patients treated with ICI alone (p = 0.033). None of the SUVratios were significantly associated with OS or PFS, although a high left colon SUVratio showed a trend toward a worse PFS.

CONCLUSION

There was no significant correlation between [18 F]FDG PET/CT uptake in different anatomical sites, and in the tumor, and systemic immune-inflammatory indexes. The prognostic role of high left colon SUVratio deserves further investigation.

The role of the caregiver in older patients with advanced prostate cancer: results from the ADHERE Prospective Study of the Meet-URO network

PURPOSE

To assess caregivers' characteristics and influence of the presence or absence of the caregiver on clinical outcomes of older (≥70 years) metastatic castration-resistant prostate cancer (mCRPC) patients treated with abiraterone (ABI) or enzalutamide (ENZ).

METHODS

Patients from the Meet-URO 5 ADHERE study were assessed with a 5-item caregiver evaluation questionnaire focusing on the presence, age, degree of kinship, working status and qualification of the caregiver. We investigated the association between the presence of a caregiver and the clinical characteristics and outcomes of enrolled patients.

RESULTS

No differences were found in the main clinical characteristics between patients with or without a caregiver, except for a lower median G8 score (p = 0.0453) in the caregiver group. A longer radiographic PFS (rPFS) was observed in the group without a caregiver, with a trend towards more prolonged overall survival (OS) in the same group.

CONCLUSION

Our work suggests a detrimental effect of caregivers in managing older mCRPC patients treated with ABI or ENZ, especially those identified as frail by the geriatric G8 screening score. Further work is needed to identify and address patients' vulnerability areas, which could have a detrimental effect on prognosis.
