Abstract:
This case demonstrates the effectiveness and ongoing potential of novel lung cancer therapies, specifically immunotherapy agents such as nivolumab, a T-cell programmed death 1 (PD-1) receptor inhibitor. In this case study, our patient had a significant burden of disease with nodal involvement above and below the diaphragm at the time of diagnosis. They were commenced on standard of care therapy: cisplatin and pemetrexed. Despite five cycles of treatment with these agents, their disease progressed significantly with the development of brain metastasis. The patient was switched to a novel immunotherapy agent, nivolumab, and had a complete response to it. Currently, there is no active disease-the lymph nodes have all regressed, the brain metastases have disappeared (with the help of stereotactic surgery) and no further metastases have developed. The patient is tolerating the treatment well and has had no significant adverse reactions to the immunotherapy agent.

Work Done During Volume Change
Consider a gas confined to a cylinder fitted with a movable piston at one end. If the gas expands from volume V1 to volume V2, it exerts a force on the piston, such that the piston moves by a distance dr.
The work done by the gas on the piston can be expressed as
Le Chatelier's Principle: Changing Temperature
To understand this phenomenon, consider the elementary reaction:
