The Difficult Task of Diagnosing Depression in Elderly People with Cancer: A Systematic Review

Background:Depression is a common psychiatric problem in the elderly and oncology patients. In elderly people with cancer, depression has a peculiar phenomenology. It has a significant impact on the quality of life. Moreover, it is associated with poor adherence to treatments, increased risk of suicide, and mortality. Nevertheless, the topic of depression in elderly people with cancer remains unexplored.Objective:The main goal of this article is to review the literature from the past 20 years on the relationships between depression, cancer, and aging.Methods:The methods followed the Prisma model for eligibility of studies. The articles in which the keywords “depression”, “cancer”, “ elderly, aging, or geriatric” were present, either in the text or in the abstract, were selected. 8.056 articles, by matching the keywords “depression and elderly and cancer,” were identified. Only 532 papers met the eligibility criteria of search limits and selection process. Out of 532 papers, 467 were considered irrelevant, leaving 65 relevant studies. Out of 65 suitable studies, 39 (60.0%) met our quality criteria and were included.Results:The risk factors associated with depression in elderly people with cancer can be divided into 4 groups: 1) tumor-related; 2) anticancer treatment-related; 3) patients-related; 4) number and type of comorbidity. The main obstacles in diagnosing depression in elderly patients with cancer are the overlap of the symptoms of cancer and side effects of treatment with the symptoms of depression but also the different ways of reporting depressive symptoms of elderly people and the different clinical types of depression. There is a lack of data regarding validated scales to assess depression in geriatric patients with cancer. Any mental illness, specifically co-occurring anxiety and depression, increases the risk of diagnosis delay and anticancer treatment adherence. Cancer and the diagnosis of mental disorders prior to cancer diagnosis correlate with an increased risk for suicide. A non-pharmacological therapeutic approach, pharmacological treatment and/or a combination of both can be used to treat elderly patients with cancer, but a detailed analysis of comorbidities and the assessment of polypharmacy is mandatory in order to avoid potential side-effects and interactions between antidepressants and the other drugs taken by the patients.Conclusion:Future research should be conducted with the aim of developing a modified and adapted assessment method for the diagnosis and treatment of depression in elderly people with cancer in order to improve their clinical outcomes and quality of life.     

Cystic lesions and scrotal fluid collections in adults: Ultrasound findings

The widespread use of scrotal ultrasonography (US) has led to increased detection of testicular and extratesticular pathologies. Cystic or encapsulated fluid collections are relatively common benign lesions that usually present as palpable testicular lumps. Most cysts arise in the epidydimis, but all anatomical structures of the scrotum can be the site of their origin. US may suggest a specific diagnosis for a wide variety of intrascrotal cystic and fluid lesions and appropriately guide therapeutic options. US should be used as an adjunctive diagnostic modality after clinical evaluation of a scrotal lesion associated or not with the presence of a lump.     

Female pseudohermaphroditism and inefficient peak bone mass in an untreated subject affected by 21-hydroxylase congenital adrenal hyperplasia

Here we describe a subject with congenital adrenal hyperplasia due to 21-hydroxylase deficiency (21-CAH), in its classical virilizing form, who presented at birth ambiguous genitalia and subsequently was assigned by the parents as male. At the age of 8 years, he underwent a two-step surgical correction of hypospadia and at 22 years old, uterus and ovaries were removed and a bilateral testicular prothesis was surgically placed in scrotum. He refused any chronic glucocorticoid therapy, that was given only acutely to prevent adrenal crises during stress, trauma surgery or severe illness. The patient is now 38 years old, he is genotypically female but phenotypically male, with high endogenous levels of androgen, all of adrenal origin, and with an apparent male sexual life. He had severe osteopenia, probably due to the lack of estrogen/androgen-induced increase in bone mineral density, although periferal estrogen conversion was normal. His skeletal mass, in fact, normally acquired during adolescence and early adult life, could in this case be inefficient, for the precocious pseudopuberty, that caused an inefficient peak bone mass in adolescence period.     

Isolated breast relapse after allogeneic bone marrow transplantation for childhood acute lymphoblastic leukemia

Unusual sites of relapses following bone marrow transplantation (BMT) for childhood acute lymphoblastic leukemia (ALL) are rarely reported. We report the case of a 16-year-old girl who presented with an isolated right breast relapse 8 months after allogeneic BMT for ALL in second remission. Biopsy showed an ALL infiltrate. Bone marrow and CSF were normal. The girl never showed before extramedullary involvement. She was treated with local radiotherapy and mild systemic chemotherapy. Nine months after breast relapse, she presented an isolated central nervous system relapse. The treatment of isolated extramedullary relapses following BMT is still controversial.

Bicalutamide monotherapy versus flutamide plus goserelin in prostate cancer: updated results of a multicentric trial

OBJECTIVES: To compare the efficacy of bicalutamide monotherapy to maximal androgen blockade in advanced prostatic cancer. PATIENTS AND METHODS: Previously untreated patients with histologically proven stage C or D (American Urological Association Staging System) disease were randomly allocated to either bicalutamide (B) or goserelin plus flutamide (G+F). After disease progression, patients treated with B were assigned to castration. The primary endpoint for this trial was overall survival. Prostate cancer-specific survival and progression were included among secondary endpoints. RESULTS: In total 108 patients received B and 112 received G+F. At a median follow-up time of 54 months (range 1-89), 151 patients progressed and 113 died. There was no significant difference in the duration of either progression-free or overall survival. Hazards of progression, death and cancer-specific death, corrected by disease stage, tumor grade and baseline PSA level, showed that patients initially assigned to B had a higher risk of progression but a comparable risk of death and cancer-specific death with the exception of patients with G3 tumors who had an increased risk of death). CONCLUSIONS: In patients with well or moderately well differentiated tumors, B monotherapy followed by castration may offer the same survival chance as maximal androgen deprivation. In those patients it thus represents a reasonable choice that can avoid the side effects of androgen deprivation for considerable periods of time.     

Evidence for corticotropin-releasing factor regulation of serotonin in the lateral septum during acute swim stress: adaptation produced by repeated swimming

RATIONALE: Swim stress decreases extracellular serotonin (5-HT) levels in the rat lateral septum, and adaptation to this effect occurs with repeated swimming. Corticotropin-releasing factor (CRF) administered into the dorsal raphe nucleus (DRN) also decreases 5-HT release in the lateral septum, suggesting that CRF may mediate the effects of swim stress. OBJECTIVES: The hypothesis that endogenous CRF mediates the reduction of 5-HT levels in the lateral septum evoked by swim stress and is involved in the adaptation that occurs with repeated swim stress was tested. METHODS: Extracellular 5-HT levels in rat lateral septum were quantified by means of in vivo microdialysis. Extracellular single unit activity was recorded from the DRN. RESULTS: Intracerebroventricular (i.c.v.) administration of a CRF receptor antagonist prevented the ability of swim stress to decrease 5-HT release in the lateral septum. Prior exposure to swim stress reduced the ability of both CRF (i.c.v.) and a subsequent swim stress to decrease lateral septum 5-HT release (cross adaptation). Additionally, the effects of CRF, administered into the DRN, on DR neuronal discharge were attenuated in rats with a history of swim stress. Finally, administration of a CRF receptor antagonist (i.c.v.) between two swim stress sessions restored the neurochemical response to swim stress (i.e., 5-HT levels were reduced during the second exposure to swim). CONCLUSIONS: Endogenous CRF modulates 5-HT transmission during acute environmental stress and is also integral to adaptation of the 5-HT response produced by repeated stress. Modulation of the 5-HT system by CRF during acute stress may underlie certain coping behaviors, while stress-induced adaptation of this effect may be involved in psychiatric manifestations of repeated stress.     

Cellular interactions between axon terminals containing endogenous opioid peptides or corticotropin-releasing factor in the rat locus coeruleus and surrounding dorsal pontine tegmentum

Recent evidence suggests that certain stressors release both endogenous opioids and corticotropin-releasing factor (CRF) to modulate activity of the locus coeruleus (LC)-norepinephrine (NE) system. In ultrastructural studies, axon terminals containing methionine(5)-enkephalin (ENK) or CRF have been shown to target LC dendrites. These findings suggested the hypothesis that both neuropeptides may coexist in common axon terminals that are positioned to have an impact on the LC. This possibility was examined by using immunofluorescence and immunoelectron microscopic analysis of the rat LC and neighboring dorsal pontine tegmentum. Ultrastructural analysis indicated that CRF- and ENK-containing axon terminals were abundant in similar portions of the neuropil and that approximately 16% of the axon terminals containing ENK were also immunoreactive for CRF. Dually labeled terminals were more frequently encountered in the "core" of the LC vs. its extranuclear dendritic zone, which included the medial parabrachial nucleus (mPB). Triple labeling for ENK, CRF, and tyrosine hydroxylase (TH) showed convergence of opioid and CRF axon terminals with noradrenergic dendrites as well as evidence for inputs to TH-labeled dendrites from dually labeled opioid/CRF axon terminals. One potential source of ENK and CRF in the dorsal pons is the central nucleus of the amygdala (CNA). To determine the relative contribution of ENK and CRF terminals from the CNA, the CNA was electrolytically lesioned. Light-level densitometry revealed robust decreases in CRF immunoreactivity in the LC and mPB on the side ipsilateral to the lesion but little or no change in ENK immunoreactivity, confirming previous studies of the mPB. Degenerating terminals from the CNA in lesioned rats were found to be in direct contact with TH-labeled dendrites. Together, these data indicate that ENK and CRF may be colocalized to a subset of individual axon terminals in the LC "core." The finding that the CNA provides, to dendrites in the area examined, a robust CRF innervation, but little or no opioid innervation, suggests that ENK and CRF axon terminals impacting LC neurons originate from distinct sources and that terminals that colocalize ENK and CRF are not from the CNA.
