Low Phase Angle Is Correlated With Worse General Condition in Patients with Advanced Cancer

Objectives: Phase angle (PA) is a poor prognostic factor in patients with advanced cancer. This study aimed to identify possible correlations between PA and symptoms, quality of life, fluid retention, and laboratory data in cancer patients in palliative care settings.

Methods: Individuals who visited the outpatient clinic or were admitted to the palliative care unit were eligible. Patients with a performance status of 4 and/or those unable to complete questionnaires were excluded. PA was evaluated using a bioanalyzer device. The correlation coefficient between PA and the variables of interest was analyzed.

Results: A total of 102 patients were analyzed. PA was weakly correlated with age (ρ = ?0.22), performance status (ρ = ?0.30), functional well-being (ρ?=?0.20), anorexia/cachexia subscale (ρ?=?0.22), and Functional Assessment of Anorexia/Cachexia Therapy trial outcome index (ρ?=?0.26). PA was also correlated with fluid retention (ρ = ?0.34) and albumin (ρ?=?0.32), C-reactive protein (ρ = ?0.31), and hemoglobin (ρ?=?0.41) levels. Sub-analysis stratified according to sex revealed that males demonstrated the same results; however, female sex demonstrated a correlation between PA and social well-being (ρ = ?0.43).

Conclusions: PA was correlated with physical condition, but not with psychological well-being.     

Primary aldosteronism due to bilateral micronodular hyperplasia and concomitant subclinical Cushing’s syndrome: A case report

BACKGROUNDAdrenal incidentaloma (AI) has been frequently encountered in the clinical setting. It has been shown that primary aldosteronism (PA) or subclinical Cushing’s syndrome (SCS) are the representative causative diseases of AI. However, the coexistence of PA and SCS has been reportedly observed. Recently, we encountered a case of AI, in which PA and SCS coexisted, confirmed by histopathological examinations after a laparoscopic adrenalectomy. We believe that there were some clinical implications in the diagnosis of the present case.CASE SUMMARYA 58-year-old man presented with lower right abdominal pain with a blood pressure of 170/100 mmHg. A subsequent computed tomography scan revealed right ureterolithiasis, which was the cause of right abdominal pain, and right AI measuring 22 mm × 25 mm. After the disappearance of right abdominal pain, subsequent endocrinological examinations were performed. Aldosterone-related evaluations, including adrenal venous sampling, revealed the presence of bilateral PA. In addition, several cortisol-related evaluations showed the presence of SCS on the right adrenal adenoma. A laparoscopic right adrenalectomy was then performed. The histopathological examination of the resected right adrenal revealed the presence of a cortisol-producing adenoma, while CYP11B2 immunoreactivity was absent in this adenoma. However, in the adjacent non-neoplastic adrenal, multiple CYP11B2-positive adrenocortical micronodules were detected, showing the presence of aldosterone-producing adrenocortical micronodules. CONCLUSIONCareful clinical and pathological examination should be performed when a patient harboring AI presents with concomitant SCS and PA.

The clinicopathological characteristics of muscle-invasive bladder recurrence in upper tract urothelial carcinoma

This study aimed to clarify the clinical characteristics and oncological outcomes of patients with upper tract urothelial carcinoma (UTUC) who developed muscle-invasive bladder cancer (MIBC) after radical nephroureterectomy (RNU). We identified 966 pTa-4N0-2M0 patients with UTUC who underwent RNU and clarified the risk factors for MIBC progression after initial intravesical recurrence (IVR). We also identified 318 patients with primary pT2-4N0-2M0 MIBC to compare the oncological outcomes with those of patients with UTUC who developed or progressed to MIBC. Furthermore, immunohistochemical examination of p53 and FGFR3 expression in tumor specimens was performed to compare UTUC of MIBC origin with primary MIBC. In total, 392 (40.6%) patients developed IVR after RNU and 46 (4.8%) developed MIBC at initial IVR or thereafter. As a result, pT1 stage on the initial IVR specimen, concomitant carcinoma in situ on the initial IVR specimen, and no intravesical adjuvant therapy after IVR were independent factors for MIBC progression. After propensity score matching adjustment, primary UTUC was a favorable indicator for cancer-specific death compared with primary MIBC. Subgroup molecular analysis revealed high FGFR3 expression in non-MIBC and MIBC specimens from primary UTUC, whereas low FGFR3 but high p53 expression was observed in specimens from primary MIBC tissue. In conclusion, our study demonstrated that patients with UTUC who develop MIBC recurrence after RNU exhibited the clinical characteristics of subsequent IVR more than those of primary UTUC. Of note, MIBC subsequent to UTUC may have favorable outcomes, probably due to the different molecular biological background compared with primary MIBC.     

Prediction of pathological complete response after neoadjuvant chemotherapy in breast cancer: comparison of diagnostic performances of dedicated breast PET,whole-body PET,and dynamic contrast-enhanced MRI

Purpose

To compare the diagnostic performance of ring-type dedicated breast PET (dbPET), whole-body PET (WBPET), and DCE-MRI for predicting pathological complete response (pCR) after neoadjuvant chemotherapy (NAC).

Methods

This prospective study included 29 women with histologically proven breast cancer on needle biopsy between July 2016 and July 2019 (age: mean 55 years; range 35–78). Patients underwent WBPET followed by ring-type dbPET and DCE-MRI pre- and post-NAC for preoperative evaluation. pCR was defined as an invasive tumor that disappeared in the breast. Standardized uptake values corrected for lean body mass (SULpeak) were calculated for dbPET and WBPET scans. Maximum tumor length was measured in DCE-MRI images.

Reduction rates were calculated for quantitative evaluation. Two radiologists independently evaluated the qualitative findings. Reduction rates and qualitative findings were compared between the pCR (n?=?7) and non-pCR (n?=?22) groups for each modality. Differences in quantitative and qualitative data between the two groups were analyzed statistically.

Results

Significant differences were observed in the reduction rates of dbPET and DCE-MRI (P?=?0.01 and 0.03, respectively) between the two groups. Univariate and multiple logistic regression analyses revealed that SULpeak reduction rates in WBPET and dbPET (P?=?0.02 and P?=?0.01, respectively) and in dbPET (odds ratio, 16.00; 95% CI 1.57–162.10; P?=?0.01) were significant indicators associated with pCR, respectively. No between-group differences were observed in qualitative findings in the three modalities.

Conclusion

SULpeak reduction rate of dbPET?>?82% was an independent indicator associated with pCR after NAC in breast cancer.

     

On-treatment C-reactive protein control could predict response to subsequent anti-PD-1 treatment in metastatic renal cell carcinoma

Objective

The aim of this study was to evaluate the clinical significance of the on-treatment C-reactive protein (CRP) status during systemic treatment as the predictive marker for the response of subsequent nivolumab monotherapy in patients with refractory metastatic renal cell carcinoma (mRCC).

Patients and methods

A total of 73 mRCC patients treated with nivolumab were retrospectively reviewed. We evaluated the serum CRP levels before and after molecular-targeted treatments. Patients whose CRP did not exceed baseline value were defined as the CRP-control group and the others were defined as the CRP-progression group. The clinical impact of CRP-control on the efficacy of nivolumab was assessed.

Results

Twenty-four patients (33%) were categorized into the CRP-control group. The CRP-control group patients (median PFS not reached) had significantly longer PFS than the CRP-progression group (median PFS 11.9 months, 95% confidence interval, CI 4.1–19.8, p?=?0.038). The CRP-control group had a tendency of longer OS from nivolumab initiation than the CRP-progression group (p?=?0.071). By multivariate analysis, the on-treatment CRP-control was the independent predictive factor for PFS (hazard ratio HR 0.37, 95% CI 0.14–0.99, p?=?0.047).

Conclusion

The on-treatment CRP-control could be the predictive factor for the efficacy of nivolumab in refractory mRCC patients.
