The efficacy and feasibility of dose-dense sequential chemotherapy for Japanese patients with breast cancer

Interstitial lung disease associated with adjuvant and neoadjuvant chemotherapy in early breast cancer

BACKGROUND

Interstitial lung disease (ILD) is a rare adverse event in patients receiving adjuvant or neoadjuvant chemotherapy (NAC) for breast cancer. Few studies have reported the frequency of ILD in detail, and only small numbers of cases have been described in the literature. Given these previous findings concerning ILD, we retrospectively examined the clinicopathological characteristics of five cases of ILD who had received epirubicin and cyclophosphamide (EC) and compared their findings with non-ILD cases.

METHODS

The present single-center retrospective study included breast cancer patients who underwent adjuvant chemotherapy or NAC at our hospital between January 2014 and January 2021.

RESULTS

Thirty-nine patients who had received EC for operable breast cancer were enrolled in this study. ILD developed 5 out of 39 patients (12.8%). The incidence of ILD in patients with non-dose-dense (dd) or dd chemotherapy was statistically significantly different (p = 0.0149). ILD occurred in three patients during dd EC treatment and two during weekly paclitaxel (wPTX) after dd EC. ILD was detected in one patient with high Krebs von den Lungen-6 (KL-6) levels, in two patients with continuous pyrexia, and in two patients from computed tomography imaging, which was taken to estimate the efficacy of chemotherapy, in two patients. Three of the 5 ILD patients underwent bronchoalveolar lavage, and 2 of these patients were diagnosed with Pneumocystis jirovecii pneumonia (PCP). There were no cases of serious ILD that required steroid pulse therapy.

CONCLUSIONS

Dd chemotherapy may be associated with an increased ILD frequency, which may reflect developing PCP. Careful monitoring and a timely diagnosis are useful for detecting early-stage ILD.

Application of positive behavior management in patients after breast cancer surgery

BACKGROUND

As a radical treatment, breast cancer surgery has a positive psychological impact on most patients. However, some patients do not have a clear understanding of the disease, which requires a more scientific and comprehensive consideration during clinical intervention and are based on cognition. The positive behavior management model is based on this kind of background-derived new interventions, which can better serve the clinical rehabilitation process of patients. The positive behavior management model based on cognitive architecture is a new type of intervention derived from this background, which can better serve the clinical rehabilitation process of patients.

AIM

To analyze the influence of a positive behavior management model based on cognitive framework on the degree of hope and self-efficacy of patients with breast cancer surgery.

METHODS

Eighty-four patients with breast cancer who underwent surgical treatment in our hospital from August 2016 to December 2018 were included in the study. The patients were divided into the experimental group (n = 42) and control group (n = 42) by random number table grouping. The control group received traditional nursing intervention, while the experimental group received a positive behavior management model based on cognitive framework based on the traditional intervention of the control group. General Self-efficacy Scale, Herth Hope Scale, Self-Rating Anxiety Scale, Self-Rating Depression Scale and Cancer Patient Specific Scale were used to evaluate the two groups before and 1 wk after intervention.

RESULTS

After the intervention, self-efficacy and hope level of the experimental group were significantly higher than those of the control group (P < 0.05). The Self-Rating Anxiety Scale and Self-Rating Depression Scale scores in the experimental group were significantly lower than those in the control group (P < 0.05). There was no significant difference in the quality of life scores between the two groups before intervention (P > 0.05). The quality of life scores in all aspects in the experimental group after intervention were significantly higher than those in the control group (P < 0.05).

CONCLUSION

The positive behavior management model based on cognitive framework applied to patients with breast cancer surgery improved hope for treatment and self-efficacy, reduced negative emotion, and improved quality of life.
